software update point error on SCCM console

[Eaven HUANG]

Dear Experts,

I'm writing to seek assistance in fixing an issue with software update point error on SCCM console - where it shows "Failures were reported on WSUS Server "sccm.edu.cn" for WSUS components "WSUSService,". Solution: Verify that the failed WSUS components are installed and running."

I checked the wsusctrl.log and got the following:
"Attempting connection to local WSUS server SMS_WSUS_CONTROL_MANAGER 11/02/2024 0:25:45 7564 (0x1D8C) Successfully connected to local WSUS server SMS_WSUS_CONTROL_MANAGER 11/02/2024 0:25:45 7564 (0x1D8C) Errors were reported in these WSUS Server components WSUSService, on WSUS Server sccm.edu.cn SMS_WSUS_CONTROL_MANAGER 11/02/2024 0:25:45 7564 (0x1D8C) Failures reported during periodic health check by the WSUS Server sccm.edu.cn. Will retry check in 57 minutes SMS_WSUS_CONTROL_MANAGER 11/02/2024 0:25:45 7564 (0x1D8C) Waiting for changes for 57 minutes SMS_WSUS_CONTROL_MANAGER 11/02/2024 0:25:45 7564 (0x1D8C)"

It was running fine for over one or two years but I lost where to troubleshoot this issue,. Any other logs I can check or what we can attempt to fix this kind of issue?
