Azure Signalr Service Issue with Blazor Application #1059

Team,

I have one application which uses the below logic ->

Step 1-> Azure SQL Database gets a row from Web API from another application and one stored procedure runs and creates an entry on the table Step 2-> once the Entry is created in this table there is one Azure Logic App which pushes the row into Queue Table in Azure Step 3 -> Once the queue table gets an entry using Queue Trigger it pushes the record to Signalr Hub where clients are connected and the record is distributed to users;

The issue I am facing here is I moved this application from Web Based to Blazor. Here when I moved this I am facing below issues a. on local system without Azure Signalr Service everything works perfectly (Only Locally) b. when I turn of the Azure Signalr Service and publish it as Web Service App and push it to Azure-> the application fails with Blazor Negotiation Error - Error Message Azure Signalr Service is not started c. When I turn on the Azure Signalr from Startup and try running it locally - it doesnt work same error Azure Signalr Service Is not Started / Connection ID Required d. When I try to push it to Web App with Azure Signalr R Service started - it doesnt work and gives me same error (Azure Signalr Service Not started / Connection Id Required)

find below blazor server logs;

Azure Signalr Service is not started

Have you configured the service correctly? https://docs.microsoft.com/azure/azure-signalr/signalr-quickstart-dotnet-core

Can you grab your server's logs and see what it says about connecting to the Azure SignalR Service?

You need to get logs from your app. https://github.com/Azure/azure-signalr/blob/82673cad4f95f6926f1e9665cf95c2815cbde55d/docs/tsg.md#500-error-when-negotiate-azure-signalr-service-is-not-connected-yet-please-try-again-later

Please provide me an update on this

vicancy commented 4 years ago

The server side, how is it configured to use Azure SignalR? Where you set the ConnectionString?

Also could you please provide your blazor app server side log following https://github.com/Azure/azure-signalr/blob/dev/docs/howto-tsg.md#add_logs_server_aspnetcore when the app server starts? We need the app server side log to identify why it fails to connect to Azure SignalR. Typically we care about logs that "Starting transport" and "Failed to connect", the log should show up right after the app server is started. The logs would be similar to below:
