Getting no response to the Service Bus API

Question

Azure Service Bus API requests are timing out using the Java SDK

Answer 1

It sounds like you're having trouble with your Azure Service Bus API requests timing out while using the Java SDK version 1.2.8. Here are some things you can try to troubleshoot this issue:

Check Connectivity: Ensure that your application has the correct network access to connect to the Azure Service Bus endpoint. You may need to verify that your firewall settings or network security groups allow outbound traffic to the Service Bus.

SDK Version: Since you are using version 1.2.8 of the Java SDK, consider upgrading to a newer version if possible, as it may contain bug fixes and performance improvements. Check the Azure SDK for Java repository for the latest version.

Debugging Timeout: Look into the timeout settings in your application configuration. The default timeout might be too low for your application’s needs, especially if you are processing large messages or if your Service Bus is under heavy load.

Inspect Service Bus Metrics: Use the Azure portal to check metrics for your Service Bus namespace. Look for metrics like incoming messages, outgoing messages, and message size to see if there might be any throttling or performance issues.

API Response: Make sure you are handling responses properly in your code. If the API is responding with errors or specific status codes, that might give you more context on why the requests are timing out.

APIM Troubleshooting: If your API is behind Azure API Management (APIM), refer to the Azure API Management Troubleshooting Series to check for issues specific to the API layer.
