Hi Jeff Ku,

Welcome to Microsoft Q&A forum.

As I understand, you're trying to connect to a MariaDB instance hosted on Azure.

Here are a few steps you can take to troubleshoot and potentially resolve this issue:

• Verify if the service has any geo-location restrictions in place. You might need to contact the service provider for this information.
• If geo-location restrictions are confirmed, using a VPN to connect from an allowed region might help.
• Ensure that your firewall and network settings are not blocking the connection. Sometimes, specific ports need to be open for the connection to succeed.
• Double-check the DNS resolution to ensure that the CNAME is correctly resolving to the intended IP address.
• Review the service configuration to ensure that it allows connections from your server's IP address.
