WSUS automated cleanup script

Hi,

I got errors while trying to run the script.

OS: Windows Server 2016 Standart
Server Version: 10.0.14393.2608
DB: WID

Error Message:
wsus-cleanup-updates-v4.ps1

Connecting to database SUSDB on MICROSOFT##WID
Unhandled exception:
Exception calling "Open" with "0" argument(s): "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. (pr
ovider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
Completed script execution with 1 error(s)
Execution time 0 hours and 0 minutes.

This is the output I receive:

WS2012 WSUS, using WID

I also receive the same error "xception calling "Open" with "0" argument(s): "A network-related or instance-specific error occurred while establishing
" . I have found this error is only on Server 2008 and Server 2008R2 systems, the script is working wel on later server versions. Is there something to change in the script for Server 2008/2008R2 to work?

Thank you

I am seeing the following error for each of the updates slated for deletion:
