I'm setting up a Tomcat server behind an Apache proxy, everything is working fine except for the forward proxy when dealing with a remote server with a self-signed certificate. I can access other HTTPS sites, but not ones with self-signed certs. I've already added the CA using SSLProxyCACertificateFile, but it still doesn't work.
In the error log, I get "AH00898: Connect to remote machine blocked returned by server_hostname".
Apache 2.4.54 on Debian 11
I can wget the URL (Once I added the CA to Debian). I can also access the URL if I allow Tomcat to bypass the proxy (When the CA is in the Java key store). But I need all the traffic to go through the proxy.
<VirtualHost 10.10.10.6:8082>
ProxyRequests On
ProxyVia On
<Proxy "*">
Require ip 10.10.10
</Proxy>
ErrorLog ${APACHE_LOG_DIR}/error_forward_proxy_secure.log
CustomLog ${APACHE_LOG_DIR}/access_forward_proxy_secure.log combined
SSLProxyCACertificateFile /var/ssl/trusted_ca.crt
</VirtualHost>
What am I doing wrong?
For a web application running on Tomcat, to support multiple SSL sites on one Ip address, I like to add Apache in front of Tomcat.
Is it possible for user to upload its own SSL certificate and configure it dynamically without server restart?
<VirtualHost *:443>
DocumentRoot
ServerName
SSLCertificateFile
SSLCertificateKeyFile
SSLCACertificateFile
SSLEngine on
</VirtualHost>
For apache, the SSL configuration above needs to be added into apache conf file,
and requires server restart. Server restart is not acceptable because there will be many users on the same server. Any solution?
Thanks for help.
I have a problem, yesterday i create certificate with let's encrypt on my ec2 instance. Now i want to use them o my site, but i don't know how i can proceed. Have you any suggestions?
I tried to do this but i hadn't any results:
https://www.paulwakeford.info/2015/11/24/letsencrypt/
than, after using webroot plugin on let's encrypt, i install mod_ssl.so on my istance, i edit my security group and enable https on port 443 and than i modify my httpd.conf right here:
<VirtualHost *:443>
DocumentRoot /var/www/my-domain
ServerName my-domain.com
SSLEngine on
SSLCertificateFile "/etc/letsencrypt/live/my-domain/cert.pem"
SSLCertificateKeyFile "/etc/letsencrypt/live/my-domain/privkey.pem"
SSLCertificateChainFile "/etc/letsencrypt/live/my-domain/chain.pem"
<Directory /var/www/my-domain>
AllowOverride All
</Directory>
</VirtualHost>
Have you any suggestions?
The tutorial you pointed out uses SSL certificate to Cloudfront distribution, a CDN. Are your using Cloudfront? Because if you are using you need to set certificate on the distribution (and maybe to apache server too), otherwise on the apache server.
Try this look into:
Enabling SSL on apache instance on EC2
and
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/SSL-on-an-instance.html
For the last, forget about "getting certificate" as you already have one issued by Lets Encrypt.
I am using WAMP 2.0 with apache 2.2.11 on windows server 2008 R2.I am setting up only one domain on this WAMP server.
i have converted the .pfx file and extracted .crt and .key file using openSSL.
In the conf/extra/httpd-ssl.conf, i have made following changes
SSLEngine on
<VirtualHost 162.62.90.11:443>
ServerAdmin webadmin#oursite.com
DocumentRoot "D:/webpages"
ServerName www.oursite.com
ErrorLog "logs/SSLerror.log"
CustomLog "logs/SSLaccess.log" common
</VirtualHost>
SSLCertificateFile "c:/wamp/bin/apache/apache2.2.11/conf/server.crt"
SSLCertificateKeyFile "c:/wamp/bin/apache/apache2.2.11/conf/server.key"
i checked in command prompt with httpd -t and i get syntax Ok.
But when i open the site with prefix https it does not open. In the error log it shows RSA certificate common name not matching with server name.
i tried replacing the IP address in virtual host with server name in certificate and the one in error log. Still it does not work.
It seems i'm missing something. Plz help me in rectifying this.
Thanx
Did you open the port 443. For example,
** <VirtualHost 192.168.0.1:443>
DocumentRoot /var/www/html2
ServerName www.yourdomain.com
SSLEngine on
SSLCertificateFile /path/to/your_domain_name.crt
SSLCertificateKeyFile /path/to/your_private.key
SSLCertificateChainFile /path/to/DigiCertCA.crt
</VirtualHost> **
when i re did the whole thing , i found https site was acessible from same webserver with prefix https.
i checked through telnet if i could connect from another domain PC
but couldn't connect.
Firewall was blocking inbound connection for port 443.added an exception and is working fine
Relieved now
Thanks to all who took time to respond and guide.
I'm trying to configure Apache on my server to work with ssl, but everytime I visit my site, I get the following message in my browser:
SSL connection error.
Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.
Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.
The error message above seems to be native to Google Chrome. However, even though the messages are different, ssl for the site is not working on any browser.
Just some background on the situation: I am using Ubuntu 10.04 desktop edition.
I installed apache by installing zend server (it installed apache automatically).
I then installed openssl. Non-https pages work fine on the site.
I tried getting trial certificates from multiple certificate sites but nothing is working (same error).
I was previously hosting my site on another server on which ssl worked just fine. I also tried using the key and cert file from that server, but I got the same error.
The domain name and IP are still the same though. My SSLCertificateFile and SSLCertificateKeyFile are pointing to the correct directory and files.
I also do not have SSLVerifyClient enabled.
If anyone has any suggestions, it would be most appreciated.
I had the same problem as #User39604, and had to follow VARIOUS advices. Since he doesnt remember the precise path he followed, let me list my path:
check if you have SSL YES using <?php echo phpinfo();?>
if necessary
A. enable ssl on apache sudo a2enmod ssl
B. install openssl sudo apt-get install openssl
C. check if port 443 is open sudo netstat -lp
D. if necessary, change /etc/apache2/ports.conf, this works
NameVirtualHost *:80
Listen 80
<IfModule mod_ssl.c>
# If you add NameVirtualHost *:443 here, you will also have to change
# the VirtualHost statement in /etc/apache2/sites-available/default-ssl
# to <VirtualHost *:443>
# Server Name Indication for SSL named virtual hosts is currently not
# supported by MSIE on Windows XP.
NameVirtualHost *:443
Listen 443
</IfModule>
<IfModule mod_gnutls.c>
Listen 443
</IfModule>
acquire a key and a certificate by
A. paying a Certificating Authority (Comodo, GoDaddy, Verisign) for a pair
B. generating your own* - see below (testing purposes ONLY)
change your configuration (in ubuntu12 /etc/apache2/httpd.conf - default is an empty file) to include a proper <VirtualHost>
(replace MYSITE.COM as well as key and cert path/name to point to your certificate and key):
<VirtualHost _default_:443>
ServerName MYSITE.COM:443
SSLEngine on
SSLCertificateKeyFile /etc/apache2/ssl/MYSITE.COM.key
SSLCertificateFile /etc/apache2/ssl/MYSITE.COM.cert
ServerAdmin MYWEBGUY#localhost
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/>

ErrorLog ${APACHE_LOG_DIR}/errorSSL.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.

</VirtualHost>
while many other virtualhost configs wil be available in /etc/apache2/sites-enabled/ and in /etc/apache2/sites-available/ it was /etc/apache2/httpd.conf that was CRUCIAL to solving all problems.
for further info:
http://wiki.vpslink.com/Enable_SSL_on_Apache2
http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html#selfcert
*generating your own certificate (self-signed) will result in a certificate whose authority the user's browser will not recognize. therefore, the browser will scream bloody murder and the user will have to "understand the risks" a dozen times before the browser actually opens up the page. so, it only works for testing purposes. having said that, this is the HOW-TO:
goto the apache folder (in ubuntu12 /etc/apache2/)
create a folder like ssl (or anything that works for you, the name is not a system requirement)
goto chosen directory /etc/apache2/ssl
run sudo openssl req -new -x509 -nodes -out MYSITE.COM.crt -keyout MYSITE.COM.key
use MYSITE.COM.crt and MYSITE.COM.key in your <VirtualHost> tag
name format is NOT under a strict system requirement, must be the same as the file :)
- names like 212-MYSITE.COM.crt, june2014-Godaddy-MYSITE.COM.crt should work.
I was getting the same error in chrome (and different one in Firefox, IE).
Also in error.log i was getting [error] [client cli.ent.ip.add] Invalid method in request \x16\x03
Following the instructions form this site I changed my configuration FROM:
<VirtualHost subdomain.domain.com:443>
ServerAdmin admin#domain.com
ServerName subdomain.domain.com
SSLEngine On
SSLCertificateFile conf/ssl/ssl.crt
SSLCertificateKeyFile conf/ssl/ssl.key
</VirtualHost>
TO:
<VirtualHost _default_:443>
ServerAdmin admin#domain.com
ServerName subdomain.domain.com
SSLEngine On
SSLCertificateFile conf/ssl/ssl.crt
SSLCertificateKeyFile conf/ssl/ssl.key
</VirtualHost>
Now it's working fine :)
Step to enable SSL correctly.
sudo a2enmod ssl
sudo apt-get install openssl
Configure the path of SSL certificates in your SSL config file (default-ssl.conf) that might be located in /etc/apache2/sites-available. I have stored certificates under /etc/apache2/ssl/
SSLEngine On
SSLCertificateFile /etc/apache2/ssl/certificate.crt
SSLCertificateChainFile /etc/apache2/ssl/ca_bundle.crt
SSLCertificateKeyFile /etc/apache2/ssl/private.key
Enable SSL config file
sudo a2ensite default-ssl.conf
A common cause I wanted to suggest for this situation:
Sometimes a customer is running Skype, which is using port 443 without their realizing it. When they go to start Tomcat or Apache, it appears to start but cannot bind with port 443. This is the exact message that the user would receive in the browser. The fix is to stop what was running on port 443 and re-start the webserver so it can bind with port 443.
The customer can re-start Skype after starting the webserver, and Skype will detect that port 443 is in use and choose a different port to use.
#Make sure that you specify the port for both http and https ie.
NameVirtualHost:80
NameVirtualHost:443
#and
<VirtualHost *:80>
<VirtualHost *:443>
#mixing * and *:443 does not work it has to be *:80 and *:443
I got this problem and the solution was a bit silly.
I am using Cloudflare which acts as a proxy to my website. In order to be able to login via SSH, I added an entry to my /etc/hosts file so I didn't need to remember my server's IP address.
xxx.xx.xx.xxx example.com
So in my browser when I went to https://www.example.com, I was using the Cloudflare proxy, and when I went to to https://example.com I was going directly to the server. Because the Cloudflare setup doesn't require you to add the intermediate certificates, I was seeing this security exception in my browser when I went to https://example.com, but https://www.example.com was working.
The solution: remove the entry from my laptop's /etc/hosts file.
If this isn't your problem, I recommend using one of the many online SSL checker tools to try diagnose your problem.
I also recommend using ping to check the IP address being reported and check it against the IP address expected.
ping https://www.example.com/
Another very helpful SSL resource is the Mozilla SSL Configuration Generator. It can generate SSL configuration for you.
I didn't know what I was doing when I started changing the Apache configuration. I picked up bits and pieces thought it was working until I ran into the same problem you encountered, specifically Chrome having this error.
What I did was comment out all the site-specific directives that are used to configure SSL verification, confirmed that Chrome let me in, reviewed the documentation before directive before re-enabling one, and restarted Apache. By carefully going through these you ought to be able to figure out which one(s) are causing your problem.
In my case, I went from this:
SSLVerifyClient optional
SSLVerifyDepth 1
SSLOptions +StdEnvVars +StrictRequire
SSLRequireSSL On
to this
<Location /sessions>
SSLRequireSSL
SSLVerifyClient require
</Location>
As you can see I had a fair number of changes to get there.
I had this error when I first followed instructions to set up the default apache2 ssl configuration, by putting a symlink for /etc/apache2/sites-available/default-ssl in /etc/apache2/sites-enabled. I then subsequently tried to add another NameVirtualHost on port 443 in another configuration file, and started getting this error.
I fixed it by deleting the /etc/apache2/sites-enabled/default-ssl symlink, and then just having these lines in another config file (httpd.conf, which probably isn't good form, but worked):
NameVirtualHost *:443
<VirtualHost *:443>
SSLEngine on
SSLCertificateChainFile /etc/apache2/ssl/chain_file.crt
SSLCertificateFile /etc/apache2/ssl/site_certificate.crt
SSLCertificateKeyFile /etc/apache2/ssl/site_key.key
ServerName www.mywebsite.com
ServerAlias www.mywebsite.com
DocumentRoot /var/www/mywebsite_root/
</VirtualHost>
I encounter this problem, because I have <VirtualHost> defined both in httpd.conf and httpd-ssl.conf.
in httpd.conf, it's defined as
<VirtualHost localhost>
in httpd-ssl.conf, it's defined as
<VirtualHost _default_:443>
The following change solved this problem, add :80 in httpd.conf
<VirtualHost localhost:80>
This is what fixed it for me on Ubuntu.
Enabled the module: a2enmod ssl
Moved all cert related files to a folder /usr/local/ssl and made it world readable: chmod -R +r /usr/local/ssl
Changed <VirtualHost *:80> to <VirtualHost *:*> in my virtual host.
Added SSLEngine On before all other SSL directives in my virtual host.
If you set a pass phrase on the cert, Apache should prompt you for it on restart.
Similar to other answers, this error can be experienced when there are no sites configured to use SSL.
I had the error when I upgraded from Debian Wheezy to Debian Jessie. The new version of Apache requires a site configuration file ending in .conf. Because my configuration file didn't, it was being ignored, and there were no others configured to serve SSL connections.
I encountered this issue, also due to misconfiguration. I was using tomcat and in the server.xml had specified my connector as such:
<Connector port="17443" SSLEnabled="true"
protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keyAlias="wrong" keystorePass="secret"
keystoreFile="/ssl/right.jks" />
When i fixed it thusly:
<Connector port="17443" SSLEnabled="true"
protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keyAlias="right" keystorePass="secret"
keystoreFile="/ssl/right.jks" />
It worked as expected. In other words, verify that you not only have the right keystore, but that you have specified the correct alias underneath it. Thanks for the invaluable hint user396404.
I solved it by commenting out:
AcceptFilter https none
in httpd.conf
according to:
http://www.apachelounge.com/viewtopic.php?t=4461
It turns out that the SSL certificate was installed improperly. Re-installing it properly fixed the problem
