APM webtop – problem with websockets for Serverside Blazor app

Hi Olof,

Have you tried to add a websocket profile to the VS  ? For client side websocket profile you might need to toggle mask payload:  

 select Remask (default; unmasks client frames for proxying/inspection, then remasks for the backend).

Use Preserve if no inspection is needed (performance with binary BlazorPack payloads in SignalR) or if remasking causes issues.

Also consider extending the handshake timeout on the Blazer app config.  Best to eliminate a timeout value maybe set for 45 or 60 seconds...Re-test and see if the handshake timeout is still appearing.  I think the underlying issue is a proxying/websocket framing issue.
