Re: Agent fails to communicate with ePO

​, hi there. first make a note of your port configuration from ePO. Go  to  Server Settings \ Ports. Now make sure these ports are open for communication on DMZ servers. the easiest way you can test is using telnet. Issue this command in Windows Command line: telnet [your ePO server] [port]


telnet 8081
