Network Monitor for App Service

I have an app service (ASP.NET .NET5) and am having some intermittent failures when POSTing to an external API using a WebClient. Periodically, it is generating an exception: "The SSL connection could not be established. Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond." I'd like to monitor packets related to the request to see if I can identify what is failing. I looked into Network Monitor, but this seems to relate only to VMs. Is there any way for me to capture the packets for my POST?

    Thanks! That gets me closer. I already had application insights configured. I can see the errors and get a bit of detail as follows:

    However, is there a way to get more details on the POST? For example... the headers used?
