ASP.NET Core 6 SignalR Client Not Receiving Messages After Reconnection
I tried several approaches but none seem to work. I'm trying to debug I'm stuck on something that should probably be simple. I'm working with an scenario with my ASP.NET Core 6 application where the SignalR client does not receive messages after it reconnects to the server. I have a setup where the client connects to a hub, sends messages, and should also receive updates from the server. However, after a disconnection and subsequent reconnection, the client seems to miss messages that are sent during that time. Here's the code for establishing the connection on the client side: ```csharp var connection = new HubConnectionBuilder() .WithUrl("https://yourserver.com/chatHub") .Build(); connection.On<string>("ReceiveMessage", (message) => { Console.WriteLine($"Received message: {message}"); }); await connection.StartAsync(); ``` I also handle reconnection logic like this: ```csharp connection.Reconnecting += (behavior) => { Console.WriteLine("Reconnecting..."); return Task.CompletedTask; }; connection.Reconnected += async (connectionId) => { Console.WriteLine("Reconnected."); // Logic to retrieve missed messages, if necessary }; ``` Despite this, if a message is sent from the server while the client is disconnected, the client does not receive it after reconnecting. I checked the logs on both the client and server side and there's no behavior during the reconnection, but the missed messages are never delivered. Is there a way to ensure that messages sent during a disconnect are queued and delivered to the client upon reconnection? I'm using SignalR version 6.0.0 for .NET 6. Any insights on how to handle this scenario or best practices for ensuring message delivery would be greatly appreciated! I'm working with C# in a Docker container on macOS.
