What’s happening?
Experiencing failures in their Power Automate flows, specifically encountering "BackendConnectionFailure" errors when using Azure Blob Storage connections.
Reason:
The "BackendConnectionFailure" error occurs when the connection to the backend service is forcibly closed by the remote host. This is often related to firewall settings on Azure Blob Storage accounts.
Resolution:
- Disable the firewall on the Azure Blob Storage account to allow connections from Power Automate and Power Apps.
- Ensure that the Azure Storage Account Access Key provided is correct and that the storage account name or endpoint is accurate.
- Verify the storage account's firewall and network settings to ensure they allow connections from the environment.
- If using Azure AD for authentication, switch the authentication type as needed (e.g., Oauth 2.0) instead of the Access Key.
- Check that the access key has sufficient permissions for required actions like creating, updating, or deleting blobs.
