Comcast blocking Arcane Legends Game Server IP

[falmear]

I've had an intermittent problem lately with connecting to Arcane Legends. Occasionally for some reason I get the error "Failed to connect to the Arcane Legends game servers. Please check your internet connection." I diagnosed the problem down to Comcast is blocking the IP 54.242.49.56 which is the current Arcane Legends game server:

Tracing route to ec2-54-242-49-56.compute-1.amazonaws.com [54.242.49.56]

The reason I know the IP is blocked is because if I do a traceroute to another IP on the same class C subnet it gets out:

Also if I use tethering from my phone I can connect from AT&T's LTE network. I filed a support case with Comcast because they are clearly blocking this IP and its not a routing issue since if it was a routing problem any other IP on the same class C would fail as well. If you're having the same problem connecting and are a Comcast subscriber I suggest you file a support case with them.
