OnlineClient is being created with null tenant id and user id on reconnect in certain situations #11777

It seems when the access token is expired and signalr reconnects to our back-end, the TenantId and UserId is null when CreateClientForCurrentConnection is called.

During debugging, I checked AuthConfigurer.SetToken and it's still being sent the old expired access token, it seems the front-end is not updating the signalr object with the new refreshed access token stored in local storage, I debugged the front-end as well and when I inspect the connection object I can see that connection.qs still has the expired access token. When I refresh the browser this fixes it though, so I am guessing this is why the TenantId and UserId is null when a client reconnects, because the access token is no longer valid. Any idea on how to fix this?

I have been trying to update the access token in the connection but no luck, how can I fix this? We have front-ends that are connected for days without refreshing and sometimes we update the back-end or restart the server and this causes the client to reconnect but now when they reconnect they don't have a TenantId or ClientId so they are not getting the messages that they should be
