Does the CDN for Microsoft Windows Update seem to be malfunctioning?
I purchased a code signing certificate, but strangely, Windows did not automatically download the missing root certificate. When I tried to manually download the root certificate according to the manual, I found that the CDN seemed to return the wrong certificate and I was unable to establish a secure connection with the website. (At least in Chinese Mainland) https://ctldl.windowsupdate.com/msdownload/update/v3/static/trustedr/en/test/authrootstl.cab Can other regions be accessed normally?
