@Stephen Roberts The error message saying that client machine is not reaching to the UK South region Gateway IP address (51.105.64.0).
Next Steps: you need to work with your internal networking team to allow this Gateway IP address from your client machine firewall. in this scenario,
- Azure SQL Server database is created in the UK South region.
- if we want to connect to any region database make sure that respective region Gateway IP address need to be allowed from the client machine firewall.
- This is a client side networking issue and For testing purposes, you can try connecting to the database from a laptop machine that is not attached to any VPN. This will help you determine if the issue is related to your client machine's firewall settings.
For more information on Azure SQL Database connectivity architecture, you can refer to the Azure SQL Database and Azure Synapse Analytics documentation on Microsoft Learn.
