I hosted an website on VMSS Azure. It’s size 4vCPU 16GB Ram.

I ran load test and the result show that some requests were timeout (by Application Gateway) because it’s take over 10 minutes (the time I set to timeout at Application Gateway)

When I look to Application Insights. It show that these requests keep verylong, from 40m to 60m but not do anything. Look like it’s in a queue.

The VMSS metrics is still not high. CPU 60% and RAM over 7GB.

Does anyone meet this issue?
