I have cloud hosting on Google, it sucks for to be honest but I am trying to get on with it, I installed LAMP stack on a VM and put my website in htdocs. When I try to access my site it gives me request timeout but sometimes it works for 5 minute or so.

When I see apache error logs , it gives me this

My website is in PHP, I haven't changed anything else other than directory permission, Is there something I am missing ?

I was having the same problem, turns out Apache has module that handles timeouts called mod_reqtimeout

The default value (you won't see it in the default http.conf) is:

RequestReadTimeout handshake=0 header=20-40,MinRate=500 body=20,MinRate=500

In my case I was uploading a file through a plain HTML form submission, so the file is technically part of the header and the default configuration says that the header will timeout at 20 to 40 seconds. The 20-40 thing is pretty cool because it will timeout at 20 seconds but if 500 bytes are sent in a second, it will add an additional second of wait time until it reaches 40 seconds and then timeout no matter what.

I upload larger files in my website so I added this line to my httpd.conf file:

RequestReadTimeout handshake=0 header=20-600,MinRate=500 body=20,MinRate=500

So as long as my user is sending data at a minimum of 500 bytes/s, the request will not time out until a max. of 600 seconds is reached (better read the documentation, don't quote me on the throughput rate)

It's actually a pretty cool Apache module but not super well known as people recommend to change other apache timeout settings in other similar "The timeout specified has expired:" problems related to PHP-FPM but this problem happens with any post that takes more than 40 seconds to be submitted by default in Apache.
