aspnetcore: Signalr Client can't communicate with server after reconnect

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

We have a issue where in rare cases after a client has lost connection to the server and reconnects it suddenly can’t acknowledges messages from server and can’t send messages to the server. Even if you restart the Client it still can’t send or acknowledge messages. But if you restart the server all works correctly again.

Expected Behavior

After it reconnects it should be possible to communicate between client & server.

Steps To Reproduce

It hasn’t been possible to reproduce this issue yet. It only happens in rare cases.

Exceptions (if any)
