500 - Internal Server Error and Gateway Timeout Error

Question

500 - Internal Server Error and Gateway Timeout Error

Muralidharan, Chetana 6

Hello,
I have deployed a python flask app onto azure as an app service with linux as the operating system. The flask application works completely fine locally. However, the web app tends to have a very high response time and works occasionally but predominantly throws 500 internal server error or 504 Gateway Time out error when called through a .net application and via postman.

Can someone help me out with this issue?

Thanks
Chetana

Hello @Muralidharan, Chetana ,
I am not a python expert, you may need to increase the timeout using the startup file please refer Flask startup section from https://learn.microsoft.com/en-us/azure/developer/python/tutorial-deploy-app-service-on-linux-04

and also make sure that the Configuration->General Settings->Always On Set to "On"

Hello @Udaiappa Ramachandran ,

The Always On setting was already set to "On". I tried adding the startup command like you suggested but unfortunately it doesn't make any change, the issue continues to persist.

I came across a query where someone tried to increase the timeout period but looks like 230 seconds is the maximum and it cannot be increased.

Is there something else I could do?
Thanks
