Azure Application Gateway Timeout #long running process

Question

We are using Azure Application Gateway with WAF. We have configured a timeout of 3600 seconds, and we performed the following scenario with Azure WAF and without WAF:

With Azure: The application runs around 1 hour and then shows 504 Error.

And without Azure, the Application got the result within 20 to 30 minutes.

Could you please help with this issue?

Answer 1

Either in Azure Application Gateway also we can get good results by doing like this

Update Backend Settings either http / https protocols request time-out to example 3600 sec

Create an health probe to test our application is working fine or not

Test the health probe, depends on the output we can figure out the issues. if any firewall block, please allow those ports from NSG.
