I have a website with Host Upon. All of a sudden on Comcast no site, email or Cpanel is available. I contacted Host Upon immediately of course. They said nothing was wrong, everything was visible on thier end and our IP address was not blocked from their servers. So with them telling me this, I transferred the internet host connection from my comcast internet connection to my Iphone personal hotspot through T-Mobile. Everything works with all website connections. But when I am hooked up to my Comcast network connection, a page comes up and says port 2083 is blocked in your network connection. Everything worked fine yesterday, Haven't touched any settings anywhere. Any help?
