Cannot access GUI. Issue with httpd.service

FreePBX System Administration
1

Hello all,
This morning I ran and update and a restart of my system. Phones work fine and i can SSH into the system without an issue, however I cannot access the web GUI.

I believe I have narrowed it down to this, but no idea how to fix it.

Looks like the httpd.service failed to start

[root@Toolroom ~]# journalctl -u httpd.service

So I checked line 165 in that file and this is what it says

   163    <Location /chatul>
   164
   165          RewriteCond %{HTTP_USER_AGENT} !(SangomaPhone|Sangoma.*Softphone|Sangoma.*Phone|Sangoma-Mobile-Chat)            RequestHeader set X-Real-IP %{REMOTE_ADDR}s
   166                  ProxyPass http://127.0.0.1:6086/chatul
   167                  ProxyPassReverse http://127.0.0.1:6086/chatul
   168    </Location>

Any help would be greatly appreciated.

looks like your SSL certificates got screwed up in Apache.

Thanks. Any suggestions on how best to fix this via SSH?

I’d start here:

Syntax error on line 165 of /etc/httpd/conf.d/ssl.conf

Thank you. I apologize, I am a bit new at all of this. Not sure what is wrong with line 165 below.

Below is the section in question from file /etc/httpd/conf.d/ssl.conf

   163    <Location /chatul>
   164
   165          RewriteCond %{HTTP_USER_AGENT} !(SangomaPhone|Sangoma.*Softphone|Sangoma.*Phone|Sangoma-Mobile-Chat)            RequestHeader set X-Real-IP %{REMOTE_ADDR}s
   166                  ProxyPass http://127.0.0.1:6086/chatul
   167                  ProxyPassReverse http://127.0.0.1:6086/chatul
   168    </Location>

Found a solution on another thread.

If anyone is having a similar issue. I used

mv /etc/httpd/conf.d/ssl.conf /etc/httpd/conf.d/ssl.conf.old
systemctl restart httpd

Now I have http admin access to the GUI again.
