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 faced the slimier issue and I fixed it by adding

skipNegotiation: true,
transport: signalR.HttpTransportType.WebSockets

in client-side as @Caims mentioned. But I don't think this is the correct solution and feel more like a hack
