Sounds like you do not know the IP address's of both ports or they were changed.

If you cannot ping them then you have the wrong IP address's.
Have you read the guide and tried the default IP address's? or looked at Feature 9*8?

Which port are you using/ LAN OAM or trying both?

You need EM then you will have Java issues because Google, Edge and Firefox no longer support Java and you will need to do a work around and so on.
IE 11 with Java and work around required.
