There are several ways in which you can set the timeout for php-fpm  In  etc php5 fpm pool d www conf I added this line   request terminate timeout   180   Also  in  etc nginx sites-available default I added the following line to the location block of the server in question   fastcgi read timeout 180    The entire location block looks like this   location     php        fastcgi pass unix  var run php5-fpm sock      fastcgi index index php      fastcgi param   SCRIPT FILENAME  document root fastcgi script name      fastcgi read timeout 180      include fastcgi params       Now just restart php-fpm and nginx and there should be no more timeouts for requests taking less than 180 seconds

Using set time limit 0  is useless when using php-fpm or similar process manager   Bottomline is not to use set time limit when using php-fpm  to increase your execution timeout  check this tutorial

You need to add extra nginx directive  for ngx http proxy module  in nginx conf  e g    proxy read timeout 300    Basically the nginx proxy read timeout directive changes the proxy timeout  the FcgidIOTimeout is for scripts that are quiet too long  and FcgidBusyTimeout is for scripts that take too long to execute   Also if you re using FastCGI application  increase these options as well   FcgidBusyTimeout 300 FcgidIOTimeout 250   Then reload nginx and PHP5-FPM   Plesk  In Plesk  you can add it in Web Server Settings under Additional nginx directives   For FastCGI check in Web Server Settings under Additional directives for HTTP   See  How to fix FastCGI timeout issues in Plesk

There are three kinds of timeouts which can occur in such a case  It can be seen that each answer is focused on only one aspect of these possibilities  So  I thought to write it down so someone visiting here in future does not need to randomly check each answer and get success without knowing which worked    Timeout the request from requester - Need to set timeout header   see the header configuration in requesting library  Timeout from nginx while making the request   before forwarding to the proxied server  eg  Huge file being uploaded Timeout after forwarding to the proxied server  server does not reply back nginx in time  eg  Time consuming scripts running at server   So the fixes for each issue are as follows    set timeout header eg  in ajax     x000D   x000D    ajax   x000D      url   test html   x000D      error  function    x000D             will fire when timeout is reached x000D         x000D      success  function    x000D            do something x000D         x000D      timeout  3000    sets timeout to 3 seconds x000D      x000D   x000D   x000D     nginx Client timeout  http        in seconds     fastcgi read timeout 600      client header timeout 600      client body timeout 600      nginx proxied server timeout  http     Time to wait for the replying server    proxy read timeout 600s        So use the one that you need  Maybe in some cases  you need all these configurations   I needed

Since you re using php-fpm you should take advantage of fastcgi finish request   for processing requests you know can take longer
