How to resolve failed to connect to database FDO error -2147215961 invalid database name

Question

I am trying to connect geodatabase on ArcMap. I get the message "[Invalid database xyz.sde.GDB_Release]

What do I need to do to resolve this error? Is there any method to check the logs from databases RDMS side or Arcgis to repair or enable geodatabase.

Arcmap version: 10.4

SQL Server version: 2012

What is the version of the geodatabase to which you are trying to connect?  From within SQL Server, query the SDE.VERSION table and report back the release it is coming back with.  Also, please provide a screenshot of the error message.
