Strange behavior this morning. Host Checker failing with "An Unexpected Error Occured" for Pulse Setup Client. These are users who are already on 9.1.11, and already had it working. I've got about 20% of windows users reporting this. Can't find a pattern. anyone else????
EDIT: turned off "Auto-upgrade Host Checker" and it works now for everyone. Do you think it's a Windows Defender update that is causing this?
