A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

Hi,

Did you try the connection with other tools such as SQLServer Management Studio? And from a different workstation?

It seems a sqlserver instance related error. Please check the firewall at the DB server/local workstation to see if it is blocking ports. I've found a similar error for another OneIdentity product that might help. Also contact your IT team.

HtH!

I would also try the UDL test from the same server where the tools are not working to rule out an issue with Identity Manager.

Thanks juancarlos camargo Troy Grandy for your response.

The issue was with the DNS settings.
