it doesn't loook right. transport is missing. what client library are you using to connect to hub?

below initial request in our case (note transport mode):

wss://XXX/signalr/connect?transport=webSockets&clientProtocol=1.5&version=3.1.878.0&connectionToken=uRCyou....&connectionData=%5B%7B%22name%22%3A%22...%22%7D%5D&tid=3

The fix has been applied.

It was URL Rewrite rules (in web config) which was the problem.
