Answer 1

Hello Mohamed Hussein,

Thanks for posting your question in the Microsoft Q&A forum.

The default timeout for Blob service operations is 30 seconds. For larger files or slower connections, this may not be sufficient. To address this:

• Increase the timeout parameter in your Logic App's Blob storage connector settings.
• If possible, set the max_single_put_size to a smaller value (4MB) to break the upload into smaller chunks

The error message suggests a network-related issue: System.Net.Sockets.SocketException (995): The I/O operation has been aborted because of either a thread exit or an application request. This could be due to:

• Intermittent network issues between your Logic App and the Blob storage.
• High latency or bandwidth constraints.

Hi Mohamed Hussein ,
Given that your file size is less than 1 MB and both your Azure Logic App and Blob Storage are in the same region (East US), the timeout issue might be related to other factors.
I suggest few steps you can take to troubleshoot the issue.
Enable Diagnostic Logging:

• Go to your Logic App in the Azure portal.
• Under Monitoring, select Diagnostic settings.
• Add a diagnostic setting to send logs to a Log Analytics workspace, Event Hub, or Storage Account. This will help you capture detailed logs for further analysis1.

Check Run History:

• In the Logic App designer, go to Overview and select Runs history.
• Review the inputs, outputs, and error messages for each step in the workflow. This can provide insights into where the issue might be occurring.

Use Retry Policies:

• Implement retry policies for actions that might fail due to transient issues. This can help mitigate temporary network issues or service disruptions.

Application Insights:

• Integrate Application Insights with your Logic App to get more detailed telemetry data. This can help you monitor performance and diagnose issues more effectively. Use scopes and the "run after" feature to handle errors gracefully. You can set up actions to run after a failure and log specific error details.

By enabling detailed logging and monitoring, you can get a clearer picture of what's causing the timeout and take appropriate steps to resolve it.
