Getting Blob resource, returns read ECONNRESET error, how can i fix this up?

Answer 1

The ECONNRESET error typically indicates that the connection was forcibly closed by the remote host. This can happen for various reasons, including network issues or misconfigurations. Here are some steps you can take to troubleshoot and resolve the issue when accessing Azure Blob Storage:

1. Check Network Connectivity: Ensure that your network connection is stable. You can try accessing other internet resources to verify that your connection is not experiencing issues.
2. Firewall and Security Settings: Make sure that your firewall or security settings are not blocking the connection to Azure Blob Storage. You may need to allow specific ports or IP addresses.
3. Endpoint Configuration: Verify that you are using the correct endpoint for Azure Blob Storage. Ensure that the URL is formatted correctly and that you are targeting the right storage account.
4. Retry Logic: Implement retry logic in your application. Sometimes, transient network issues can cause connection resets, and retrying the request may succeed.
5. Check Azure Status: Visit the Azure status page to see if there are any ongoing issues with Azure services that could be affecting connectivity.
6. Use Azure Storage Explorer: If possible, try accessing the Blob Storage using Azure Storage Explorer to see if the issue persists there. This can help determine if the problem is with your application or the network.

If the problem continues after these steps, consider reaching out to Azure support for further assistance.

Answer 2

Hello Lulixue Lu,

Thanks for posting question in Microsoft Q&A forum,

You are seeing a “read ECONNRESET” error while connecting to Azure Blob Storage through the China Mobile 4G network. This typically happens when the network connection is abruptly interrupted or reset during communication with the storage service.

Here are a few things you can try to troubleshoot the issue:

1. Check Network Connectivity: Since you're using a mobile network, make sure your connection is stable. Try switching to a different network or using a more reliable internet source to rule out local connectivity issues.
2. Timeout Settings: If the operation takes too long, you may encounter connection resets. Check your timeout settings and increase them if necessary.
3. Inspect Network Configuration: If you have any firewall or proxy settings, ensure they aren’t blocking the traffic to Azure Blob storage. You can also try accessing the Blob storage from a different device or network configuration.
4. Test Different Blob URIs: If you are using a specific endpoint, try accessing a different blob to see if the error is consistent.
5. Use Diagnostic Tools: You can utilize Azure’s diagnostic insights to check for any underlying issues with your Azure Blob resource.
6. Check Azure Service Status: Sometimes, the Azure service itself may be undergoing maintenance or facing outages. Check the Azure status page for any ongoing incidents.

If you continue facing this issue, consider providing the following details for more targeted assistance:

• What specific SDK or tool are you using to access the Blob storage?
• Can you share any specific HTTP error codes you are receiving along with the ECONNRESET message?
• Is this issue happening with all blobs or just specific ones?
• Are you using an Azure Storage Explorer or any other tool to access the resources?

Hope this helps you get on the right track! If you have more questions, feel free to ask.
