Hi. In a site that is currently in 2103, we'd like to peform an in-place upgrade to Version 2203 via Update and Servicing. But in the "Update and Servicing" tab, I can only see a single "Configuration Manager 2103" in the tab. Our "service and connection point" was offline before and it was switched to "Online" now. But we still cannot see anything shows up in the tab even after clicking "Check for updates" for a few days.
I've tried the Microsoft's troubleshooting steps for Updates and Servicing and found the following warnings in dmpdownloader.log:
After some research, I tried following the "Case 2" of the troubleshooting steps and tried the connection with the URL http://download.windowsupdate.com/windowsupdate/redist/standalone/7.4.7600.226/windowsupdateagent30-x86.exe but the file was successfully downloaded.

Then I tried to follow service-connection-point-not-download-updates but checked that the Baltimore CyberTrust Root certificate is present and the status is ok. I have run out of ideas now. Has anyone experienced this before? How can I get the updates to show up ini Updates and Servicing? Thanks.
