Answer 1

Hello,

 

Thank you for posting in Q&A forum.

To further troubleshoot this issue, please kindly try below steps:

1.Ensure that Update Services, IIS Services, and SQL services are running properly on the server. Restart the service if necessary.

2.Check if there's any firewall settings that could block the necessary ports for WSUS communication.

3.Try to clear WSUS cache and see if it helps.

4.Check WSUS log for any additional error messages or insigts that might help identify the RCA.

 

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

 

Best regards，

Jill Zhou
