Ack-able message Microsoft.Azure.SignalR.Protocol.JoinGroupWithAckMessage waiting for ack timed out.

See original GitHub issue

Describe the bug

when adding a user to a group I get this error:

[2021-02-22 08:37:04Z WRN] Failed to send message null. System.TimeoutException: Ack-able message Microsoft.Azure.SignalR.Protocol.JoinGroupWithAckMessage waiting for ack timed out. at Microsoft.Azure.SignalR.ServiceConnectionContainerBase.WriteAckableMessageAsync(ServiceMessage serviceMessage, CancellationToken cancellationToken) at Microsoft.Azure.SignalR.MultiEndpointMessageWriter.<>c__DisplayClass8_0.<<WriteAckableMessageAsync>b__0>d.MoveNext() — End of stack trace from previous location — at Microsoft.Azure.SignalR.MultiEndpointMessageWriter.<>c__DisplayClass9_0.<<WriteMultiEndpointMessageAsync>b__2>d.MoveNext() — End of stack trace from previous location — at Microsoft.Azure.SignalR.MultiEndpointMessageWriter.WriteAckableMessageAsync(ServiceMessage serviceMessage, CancellationToken cancellationToken) at Microsoft.Azure.SignalR.ServiceLifetimeManagerBase1.WriteCoreAsync[T](T message, Func2 task)

To Reproduce

call await Groups.AddToGroupAsync(Context.ConnectionId, “groupid”, Context.ConnectionAborted); in OnConnectedAsync() in a hub. Occurs most of the time, but not always. Happens even with barely any server load.

Further technical details

Microsoft.Azure.SignalR 1.7.1 in .NET 5 (linux docker container)

Happening to me as well. Don’t have reproduction but it’s showing up from time to time in our logs. .Net 5 with Microsoft.Azure.SignalR 1.12.0 installed. We are running Azure SignalR standard with 1 unit.
