Hello,

You can get this error while connecting SQL database remotely. This typically implies that you need to update your SSMS client software.

You can read the details at:

It seems you have migrated your database to the latest version of SQL Server (2012) platform, and that is when the issue cropped up. Updating your client to either a newer version of SSMS, or with the latest patches for your existing version should make the error go away. After upgrade SSMS version you will be able to access SQL database without any issue.

Thank you,
