Failed to Connect to Azure Storage - Causes and Solutions

Connecting to Azure Storage can be a straightforward process, but sometimes you may encounter issues. This is often due to incorrect Azure Storage account credentials.

One common cause of connection issues is an incorrect Azure Storage account name or key. Make sure you're using the correct credentials.

Another possible cause is a misconfigured firewall rule, which can block access to Azure Storage. This can be easily fixed by updating the rule to allow incoming traffic.

Troubleshooting Azure Storage can be a challenge, but there are some common issues to look out for.

If you're trying to connect to Azure Storage using Azure Storage Explorer with a Private Endpoint, you might encounter an error. In this case, try doing an nslookup over the storage account – it should resolve to a private IP, which you can verify from the IP assigned to the FQDN under private endpoint configuration.

The connection might be established, but the actual error might appear when you try to perform listing or other operations. A common error you might get is "unable to retrieve child resources", but the key is to check the error details and see what it points to.

If the error points to a "403 - Authorization Error", you need to investigate further. This could be due to insufficient roles, Firewall and VNET configurations, or other issues. Make sure you have the right access in place.

In case the error points to "Account Does Not Exist", verify that the account exists and hasn't been deleted. If you're using a Hosts File to specify the IP of the storage account, ensure that you have the updated public IP mentioned in the host file entry. You can find the Hosts file at C:\Windows\System32\drivers\etc.
