I checked Telnet, it's succeeding to connect to the EEI Server
Can't think of what else is missing here. 
Version 1.8.2218
Both computers are on a network connected via site to site VPN to the EEIserver network. there is another computer on that network, that did not report the "can not connect to ESET Inspect Server" error while those 2 did. 
It's log looks like this:

Much cleaner of errors. 

 

I did reinstall EEI twice - first time the error continued showing on EPConsole, Second time I uninstalled + removed the old ESET Inspector folder (old gen name) - 
the Yellow warning vanished but I still see all these errors.

 

Any thoughts?

Hello @avielc,

please enable the debug logging for the EI Connector for an hour, collect the logs and provide us with them to check.

Do not forget to set the logging verbosity back afterwards.
