Hi, @golden alick

Thank you for posting in Microsoft Q&A forum.

To troubleshoot this issue, you can follow these steps:

1. Verify that the Update Services service is running on the WSUS server.
2. Verify that the Default website or WSUS Administration website is running on the WSUS server.
3. Check the port settings configured for the software update point. Verify that they're the same as the port settings configured for the website used by WSUS running on the software update point.
4. Review WSUSCtrl.log for more errors.
