I configured httpd.conf for websockets, I am not able to establish a connection, I am getting “error reading status line from remote server”
Below are the errors and the configuration.

I have installed Apache 2.4.6 on Centos7 official.
httpd.conf was not changed from default.
Configured webdav.conf with the following:
DavLockDB /var/www/html/DavLock
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/html/webdav/
ErrorLog /var/log/httpd/error.log
CustomLog /var/log/httpd/access.log combined
Alias /webdav /var/www/html/webdav
<Directory /var/www/html/webdav>
DAV On
</Directory>
</VirtualHost>
webdav directory has 755 rights. DavLock not created.
I keep getting this error and not sure what the cause might be. Have tried many things without success:
[Fri Jan 29 11:41:17.027110 2021] [dav:error] [pid 15068] [client xxx.xxx.xxx.xxx:53946] The locks could not be queried for verification against a possible "If:" header. [500, #0]

any ideas are welcome
Got it working now.
all files/folders under /var/www/ are chown to apache
moved DavLock to here: /var/lib/dav/
and added this line under httpd.conf:
<IfModule mod_dav_fs.c>
# Location of the WebDAV lock database.
DAVLockDB /var/lib/dav/DavLock
</IfModule>
At this point, I am getting 403 error. Solved by executing the following:
chcon -R -t httpd_sys_content_rw_t /var/www/html/webdav/

The problem is: when I open mniek.ru, I'm getting to my website. Also, when I go to httpme.tk, I'm also getting to my website, not to my flask application. What's wrong?
Application is not working and failing with below reason. Could someone please help on this.

I'm trying to build a website which requires the Stripe payment gateway, and therefore requires SSL. I'm using XAMPP on Windows 10. After generating SSL certificate and key pair and installing in Apache, Apache no longer starts.
I'm attaching a few error messages and configs. Please help.
This is message in Apache error log. It no longer reproduces these error messages. So something must've changed. I think I tried generating the certificate and key via a different method. But Apache still won't start.

Am I missing anything?
I commented out Listen 443 in httpd-ssl.conf (C:\xampp\apache\conf\extra) and now Apache starts and the site is available on https and http. There must already be a directive elsewhere directing Apache to listen on 443 ...
#
# When we also provide SSL we have to listen to the
# standard HTTP port (see above) and to the HTTPS port
#
#Listen 443
I configured apache server as a reverse proxy and it works fine if I point a backend server as HTTP. That is:
I configured virtual host 443 like:
ProxyPass /primary/store http://localhost:9763/store/
ProxyPassReverse /primary/store http://localhost:9763/store/
Here users will access the server like https://localhost/primary/store
And this works fine... But I want to configure HTTP server like;
ProxyPass /primary/store https://localhost:9443/store/
ProxyPassReverse /primary/store https://localhost:9443/store/
When I configure like apache server gives 500 internal server error. What am I doing wrong here?
The error I get is:
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, you#example.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
In the apache error log it states;
nt: SSLProxyEngine]
[Mon Aug 04 00:03:26 2014] [error] proxy: HTTPS: failed to enable ssl support for [::1]:9443 (localhost)

[Mon Aug 04 00:03:51 2014] [error] proxy: HTTPS: failed to enable ssl support for [::1]:9443 (localhost)
How to configure http server to talk to HTTPS server?
Your server tells you exactly what you need : [Hint: SSLProxyEngine]
You need to add that directive to your VirtualHost before the Proxy directives :
SSLProxyEngine on
ProxyPass /primary/store https://localhost:9763/store/
ProxyPassReverse /primary/store https://localhost:9763/store/
See the doc for more detail.
In my case, my server was configured to work only in https mode, and error occured when I try to access http mode. So changing http://my-service to https://my-service helped.
