Asked by Sam W
Hi i just deployed a 1-click PHP app, (webonyx/grqphql) from gitlabs, it compiles and deploys fine but when i try to hit the app from my browser i’m getting crashes with ‘Failed to read FastCGI header’ without a clue as to what is causing the crash - i’ve tried increasing the PHP memory limit to 256, but have run out of other ideas… the PHP app of course runs fine locally…
the console log is this:

Heya @samwangler,
The errors I see from the log are
This usually would mean a problem with the application you are hosting however can you post your configuration file just for us to be sure?
Heya, @samwangler
You can double-check if the PHP-FPM settings are not set to a low value, this will be for the
max_execution_timeandrequest_terminate_timeoutAnother approach will be to use PHP Debugging tools like tools like Xdebug to identify performance bottlenecks. This can help pinpoint specific areas of your code that are causing delays.
Hope that this helps!
