I see you already set fastcgi_read_timeout to a high value on your server,
so the problem may lie on the PHP side.

Check your max_execution_time (have a look at the memory limits aswell) in
php.ini to make sure PHP itself does not trigger a timeout. You should also
make sure that your script does not use output buffering (and also disable
output buffering in php.ini), and it flushes its output immediately (check
out the implicit_flush directive on php.ini).

greetings,
alex
