If you're having trouble accessing your Azure Storage files through the Azure Front Door endpoint, here are some steps you can check:
- Verify Configuration: Ensure that your Azure Front Door is correctly configured to point to your Azure Blob Storage account. Check that the origin hostname is set correctly.
- Public Access: Make sure that the blobs in your storage account are publicly accessible if you are not using Shared Access Signatures (SAS). If the blobs are private, you will need to use SAS to grant access.
- Firewall Settings: Check the Azure Storage firewall settings. If your storage account is configured to deny public network access, ensure that Azure Front Door is allowed to access it through the Private Link or by allowlisting the Front Door service tag.
- Caching Issues: If you have recently updated the blobs, remember that Azure Front Door caches content. If the content has been cached, it may not reflect the latest changes until the cache expires or is purged.
- WAF Configuration: If you have a Web Application Firewall (WAF) enabled, ensure that it is not blocking the requests to your storage account. You may need to adjust the WAF rules to allow traffic.
- Custom Domain: If you are using a custom domain, ensure that it is properly configured and that the CNAME records are set correctly to point to your Azure Front Door endpoint.
By checking these configurations, you should be able to troubleshoot the connection issues between Azure Front Door and your Blob Storage.
