EVERY TIME, I have a new Server from HostWay, I face trouble with WHM Access, I post ticket toHostWay to Resolve the Issue for me. But Now as I know how they do it for me, I should do it myself, getting older, forget things, so sharing it, Now, no chance to forget.  All that I will have to do is enabling the port 2087 in Sentry Firewall.
