For testing puropuse i updated my workstation to 9.0.2032.2 and the error appeared, not in 8.0 versions or lower.
I have over 90 workstations connected to Eset Protect so turning off proxy polixy is not an option.
ESET Management Agent 9.0.1141.0, ESET PROTECT (Server), ver. 9.0 (9.0.2144.0) in VA.
