I have hosted a site in IIS (Version 10.0.16299) on windows 10.
My site running under SSL required. When my site running with SSL required I am getting error
403 - Forbidden: Access is denied.
But when I disable required SSL, I am not receiving this kind of error everything is working fine.
But in my case, it is a must to use a required SSL connection.
The IIS hosted site is a simple directory browsing site.
How can I use it with the required SSL?
And I have attached the Trace root are in the below link.
Failed Trace root file
I reviewed your FRT log and the error message is 403.7-Client certificate required.
It is obviously that you are Setting Client certificates to required. If you don't need client certificate authentication for your web application, then Require is not required.
If you just want to enable SSL for your https site,Check Require SSL and set client certificate to ignore is enough.
Please keep in mind that you need to Set Client Certificates to required only when your web app require to pass client certificate from client side
It's a certification related issue we observed and resolved when installed the right certificate in the trusted root.
Configuration need to change on IIS
Occurrence of 403 is not only particular instance, it's IIS configuration part, in most case you can resolve from IIS it's self, there might be some restriction level in IIS setting, you can check on IIS where your site hosted, find IP Address and Domain Restrictions option and check there will an entry to allow specif IP address, we need to update that entry by checking Edit Feature Settings... enter image description here then need to select Access for unspecified clients: earlier may be Deny instead of this we need to allow enter image description here. after those changes, your url available to access if you have same issue which I described.

I tried to setup automatic Let's Encrypt certification for a domain using this libray
It is easy to setup and I hosted it in IIS.After some errors couldn't make it work.
Finally I tried running app with Kestrel as end server, without IIS and i automatically got certificate and everything worked fine.
But my requirement is IIS hosted application because I already have some applications hosted on IIS all of them behind port 80/applicationName/
First problem I came upon is and also my first question: How can I even get to application using https(to auto get certificate) when I can't add IIS binding without certificate?
I assumed I must UseHsts() and UseHttpsRedirection() so I added it to startup of my application.
After some time and few different combinations of settings I got it work partially.
My application got certificate from LetsEncrypt and reported no errors, but when I access it in browser on http I get redirect to https and nothing there.(Still no binding for https in IIS).
My second question would be: How to properly configure https redirection from IIS to Kestrel in order to use my automatically acquired certificate?
create a dummy certificate in IIS, assign it to your site, save.
Go into IIS again and delete that certificate, if you check your bindings you'll find it as https, but certificate is empty.
Thanks
I have a website host on IIS 10 and installed wild card SSL. The website is working fine on all other machines and on the server as well. When i access it on my window 10 machine, it is asking to confirm the security certificate and credentials. If i press the ok button the site went to 403 Forbidden error.
This issue was related to the server. My Hosting provider has made the following changes at IIS.
IIS -> Websites -> Go to website -> SSL settings
client certificate to ignore
We've an ASP.NET MVC4 app where there is a part which should be secured through client certificates.
When anyone wants to connect to this part of the app, browsers should ask them for a client certificate, once they select it, our server will get it, check it's validity and show the content.
Ok, I'm getting trouble with the select certificate part. Before setting it just to one folder on views content, I'm trying to configure this on the global app.
I've set SSL to be required, and also set require client certificates on SSL Configuration on apps configuration on IIS.
I've enabled the iisClientCertificateMappingAuthentication (although I've set no mapping yet)
When I try to access the app both, Firefox and Chrome, return a 403 forbidden error, stating that I have no access to the app with the credentials provided.
I've a client certificate installed on my local machine and the CA who created this certificate as a trusted root certificate on server local machine.
I'm not being prompted for certificate.
If I uncheck the "require" from client certificates on SSL Settings, I can access the app through https.
This is the first time I work with client certificates, so it's being a bit confusing and maybe I'm not giving enough info. Feel fre to ask for further info on the comments.
EDIT: I've exported the client certificate, copied it to the server and checked it there. The certificate shows as valid and every element in the certification chain seems to be recognized in the server.
I've checked IIS logs also, and the error I'm getting is 403.7, so the certificate is not being issued to the server or it's invalid.
Now... I've checked that the certificate is valid on the server, it's correctly installed on the client but it's not getting to the server or is not beign validated there... what am I missing here?
Ok, finally I've found the problem, it's related to the buffer size reserved for the list of trusted certification authorities.
Check this kb article:
https://support.microsoft.com/en-us/kb/933430
TL DR; To solve the problem just add a new entry in the registry at:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL
named SendTrustedIssuerList as a DWORD value with value 0.
This way, the server won't send the trusted certification authorities list, so browsers will display the complete list of certificates to the user.
I have an application integrated with keycloak. THe application runs on wildfly server. I use web.xml to authenticate keycloak(as Login config). Apart from that i use keycloak.json file, where i define the keycloak realm settings in application.
When i invoke the application pages, the keycloak login pages opens, after entereing the credentials, it comes back to wildfly with 403 forbidden error.
Previously, the same setup was working but now after enabling ssl, i'm facing this issue.
Please help me in resolving the issue, does it require any other additional setup for ssl.
If its the case that login is failing after SSL was enabled it would be because SSL certificate was not in the truststore and you might this exception javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
For this you can disable-trust-manager , by adding the following conf in keycloak.json
{
...
"disable-trust-manager": true
}
If this solves the issue then the proper way of doing it will be to add the certificate to the trust store and specifying it in keycloak.json file like so.
{
...
"truststore": "cacerts.jks",
"truststore-password" : "password"
}
The problem was with the keycloak configuration. The roles created for my application did not have scope. after enabling the role to full scope, the issue got resolved.
As the setup worked without SSL, a scope related issue might not result in 403 error. Instead, connectivity from client application server to IDP server over the IDP HTTPS port can be tested first (can use telnet).
Else, it can be SSL certificate verification issue, as answered by #Shiva. Just to add to it, ideally, a valid CA certificate may not create trust issue. In such a case, supported browsers and java versions for your IDP certificate's CA can be checked. Just upgrading to latest java version or adding the CA's root certificate to your default trust store can solve such problems. This will not require any changes to the keycloak.json file.

P.S: As I could not add a comment, added these points here.
I would like to make my azure web site as https enabled one. As exactly like https://mysite.azurewebsites.net. Though I have uploaded my SSL certificate in certificate section in web site configuration tab its not redirecting automatically. Is there any other settings I have to enable?
Appreciate your help.
So to clarify the sequence of steps:
After you configure your custom domain properly, then h_ttp://customdomain.com will point to mysite.azurewebsites.net.
After you bind an SSL certificate to a custom domain in a web app, then h_ttps://customdomain.com will point to mysite.azurewebsites.net, using the bound SSL cert. If you still can't access h_ttps://customdomain.com, then you need to check whether you've configured your domain records properly at the domain registrar.
At this point, h_ttp://customdomain.com will continue to work. If you want to enforce HTTPS for your web app, see http://azure.microsoft.com/en-us/documentation/articles/web-sites-configure-ssl-certificate/#bkmk_enforce.
