My application gateway is having 2 instances of web API & UI , and while running many times i am getting gateway timeout (504 error) , also while doing load testing from JMeter , Web APIs are getting gateway timeout error very frequently ,even though the App services are having standard tier and timeout is given as 300 seconds in application gateway health probe .
Kindly suggest a way to run the app services with 504 error .
Hi
how have you got App Gateway set up for Min-max Instances? Check this to make sure your baseline load is set up correctly:
Also check App Gateway Insights in the Monitoring section to see how many compute units are being used when your App is running at full load.
Final thing - how is your JMeter set up to ramp up? Is it instant or over a period of time?
Hope this helps,
Thanks

@Michael Durkan Capacity type for application gateway is set to Manual and instance count is 2 .
Compute units when App is running at full load is approx. 2 .
Ramp up period is set to 1 second for 200 users (number of threads)
Hi,
The error 504 gateway timeout usually occurs when one or more servers could not complete the request within the allotted time and does not receive a timely response from gateway.
You can increase the timeout of your backend as below:

Hi @msrini-MSFT , i observed that the performance is not consistent when using application gateway ,I have an application gateway with tier WAF V2, Capacity type: Manual, Instance count: 2, it has 2 backend app services ,when i was directly using the app service it was much faster , can you suggest how can i make the performance consistent .
