Greetings!

It looks like you’re using mod_fcgid, and the back-end application is not responding before the timeout value. Raising the timeout is certainly an option, and it can be a stand-in solution for the moment, but I have a problem with calling it “the” solution. If a timeout has to be extended to load a website, then I propose that said website needs to have it’s code reviewed for performance issues. You want your website to be fast, and this is evidence that it is not.

With that said, let’s go ahead with the idea of increasing the timeout. I do not know what configurations you’ve made, so I will suggest doing this to identify where the configurations may be:

grep -R "Fcgid" /etc/apache2

This should reveal what files have that string in them. You may find many different variables with timeout values assigned. You can find a reference to each one of these variables and how they can be configured here:
