Hi,
Thanks for posting in Microsoft Q&A forum.
You could try to specify the correct port that WSUS is listening on in CommonSettings.ini, for example:
WSUSServer=http://WSUSServerName:8530
Similar thread for your reference:
Task sequence failure - ZTIWindowsUpdate
MDT Task sequence fails to install windows updates from local WSUS server -2145107943 0x80244019
Hope it helps. Thanks for your time.
Best regards,
Simon
