Describe the bug

There is already a ticket reported for this but is closed without proposing any solution. https://github.com/dotnet/aspnetcore/issues/39811

I am trying to test SignalR reconnected scenarios and a weird thing is happening that has caught my attention. If I turn off my wifi and reconnect it, my SignalR connection is reconnected successfully.

But soon after a few seconds, my web socket connection gets closed and the below-given log is printed in the console.

[2022-06-05T13:34:26.650Z] Trace: (WebSockets transport) sending data. String data of length 11. Utils.ts:192 
[2022-06-05T13:34:34.703Z] Trace: (WebSockets transport) data received. String data of length 10683. Utils.ts:192

[2022-06-05T13:35:34.767Z] Error: Connection disconnected with error 'Error: Server timeout elapsed without receiving a message from the server.'. Utils.ts:182

This is happening both in Chrome (102.0.5005.63 (Official Build) (64-bit)) and Edge (102.0.1245.30 (Official build) (64-bit)).

Expected Behavior

After reconnection, the SignalR connection should stay connected.

Steps To Reproduce

1. Establish a SignalR connection with logging level trace.
2. Close/Disconnect Wifi
3. Wait for SignalR to go in reconnecting state
4. Connect Wifi again
5. Wait for SignalR to go in reconnected state
6. Wait for 60 seconds max
7. Open console and observe logs, you will be able to see this pattern.

Exceptions (if any)

Error: Connection disconnected with error 'Error: Server timeout elapsed without receiving a message from the server.'

.NET Core Version

3.1.1

Anything else?

Nuget package: Microsoft.AspNetCore.SignalR: 1.1.0 Client library: "@microsoft/signalr": "^5.0.7"

[rafikiassumani-msft]

@asadmalik3 Triage: Since you are using 3.1.1, you do need the following package anymore: Microsoft.AspNetCore.SignalR: 1.1.0. On the client side can you use @microsoft/signalr 3.1.23 (https://www.npmjs.com/package/@microsoft/signalr/v/3.1.23) ?

[BrennanConroy]

Please try the 6.0.x or 7.0.x version of the @microsoft/signalr package, 5.0.x isn't supported.

Additionally, please provide a minimal repro application as a github repository.
