I have WSUS v.6.3.9600.18838 working on Windows Server 2012 R2.
After each synchronization, errors appear in the program log when checking the certificate of the update file kb4022730. I looked through the log for a month and I see no other errors. Please help solve the problem.
Full text of errors:
10032 The server cannot download some updates.
364 Error downloading content file.
Reason: File cert verification failure.
