To address the issue of SignalR not delivering messages,Access the Azure Portal.->Navigate to your SignalR Service instance.
Select Diagnose and solve problems.
Investigate any reported outages, throttling incidents, or system errors.
In the Azure Monitor, go to Alerts.
Your alert rule indicates that System Errors are occurring.
Review the detailed error messages to identify the root cause.
Within your SignalR Service instance, select Metrics.
Monitor key metrics such as Server Connections, Message Count, and Errors.
If Application Insights is configured, examine the logs for any anomalies.
Confirm that the server maintains a stable connection to the SignalR service.
Ensure clients are successfully connecting and receiving messages.
For setups utilizing Serverless mode, verify that the associated functions or services are operational.
If employing Azure Active Directory (AD) or JSON Web Tokens (JWT) for authentication, check for expired tokens or altered permissions.
Dispatch a basic test message,
await hubContext.Clients.All.SendAsync("ReceiveMessage", "Test Message");If this message is received, potential issues may include client-side filtering or message serialization problems.
Restart both the SignalR Service and your associated web application or backend services.
If recent updates were applied, consider reverting to a prior stable version to determine if the update introduced the issue.
