I am running an old application that has been deployed to VM that is running on the cloud. When using Edge or IE11 the app is working fine for a few minutes before it starts giving me the error in question. But in Chrome it fails on the first run. Dev. console says 504. Application log looks fine, seems like the app. responses with 200 to the failing call. Feels like the problem is in between the app and IIS or maybe the network. Any idea how to trouble shot that kind of problem?
Thanks
