To avoid 502 error, you should:check where the bottleneck is firstly.
Do you run php as fastcgi server, and 502 occurs when you access a PHP
page? If so, you would want to increase the size of buffer for fastcgi
communication. And, optimize the php script executive time is also
needed. E.g., optimize the database, in order to decrease the
executive time.
