Angular/SignalR Error: Failed to complete negotiation with the server

Question

Using SignalR for my server and Angular for my client... When I run my client I receive these errors:

zone.js:2969 OPTIONS https://localhost:27967/chat/negot         


        

Answer 1

I had the same problem, and it turns out that the launchSettings.json in the part where it says signalRchatServer does nothing, the url that worked with me was that of the iisexpress, I say it because there are many places where they say that the url is the one below .
