Error: Cross-Origin Read Blocking (CORB) during negotiation request

[georglang]

I can´t establish my connections anymore.

I got the following Message in Chrome (Version 83.0.4103.97):
"Cross-Origin Read Blocking (CORB) blocked cross-origin response http://..../signalr/signalr/negotiate?clientProtocol=2.1&connectionData=%5B%7B%22name%22%3A%22reporthub%22%7D%5D&callback=jQuery34101394205021301631_1598850956466&_=1598850956467 with MIME type text/html.
