Unhandled WinHttpException

[JustArchi]

This looks like something that should be catched in SK2 internals, thanks!

Quoting user, this has something to do with waking up PC after sleeping. Ref: JustArchiNET/ArchiSteamFarm#586 (comment)

Another one for the same issue:

Hmm, so RecieveAsync can throw WinHttpException, which is a corefx-internal subclass of Win32Exception. Looks like MS docs don't list possible exception types for websockets.
