EEI | Can't connect to EEI-Server

[avielc 54]

Hi
I had some issue where computers suddenly stopped sending logs to the clients, after a while I figured it was related to the upgrade of client's version to the latest(1764), while the server was on previous version(1755)
so now there are still a few machines (mostly Windows ) 
That receive this error in the log:

Any ideas how can I fix this?

This will probably require further troubleshooting and logs. Please open a support ticket and provide both EIAgent logs and EIServer logs for perusal.
