SQL Connection Error: received certificate has expired

Hi z3pp4 

1. Check the SQL Server's Certificate

Ask your IT or DB admin to check the installed certificate’s expiry.

You can also check via mmc >> Certificates >> Personal >> Certificates on the server.

2. Update/Renew the Certificate

Generate and install a new SSL certificate.

Use SQL Server Configuration Manager >> Protocols for MSSQLSERVER >> Properties >> Certificate tab to apply it.

3. Restart SQL Server

After applying the new certificate, restart the SQL Server service for changes to take effect.
