Client Security Upgrade from 14.10 to 15.11 failed
All the Windows clients are running 14.10 and there is no connectivity problem with Policy Manager Console (running version 15.11) so far, at least their AV definition are up-to-date.
When I upgraded them through Policy-based installations, all failed with "Failed: download interrupted". Can someone advise what I can troubleshoot further please?
This fail indicates some network issue happened while the client is downloading the installer from PM Server.
You can try to do one more attempt. If the installation will fail again, we will need diagnostic information from Policy Manager, and affected client(s) for investigation.
Thank you Vad for your response!
Provided that the clients are able to download AV definition updates, is there any additional TCP/UDP connection required for downloading installer?0
Thanks Vad. Probably I will open a TAC case for further investigation.0
