Sorry guys, Creeperhost is quite iffy currently, and I don't know why. Ill look into it best I can, but my best advice is to follow these steps:
-Close minecraft
-Restart FTB Launcher
-Run Minecrack
-Attempt to connect
Ive seen a couple people connect, and then lose the opportunity later. I think its because CreeperHost is being DDoS'd potentially, as even their Control Panel is slow, and Ive NEVER had an issue like this before.
EDIT: I definitely think its something CreeperHost side, namely via authentication. Deadly was able to make it on earlier, and we are both fine right now, no lag, no disconnects etc. Five minutes ago the CP worked great, now its slowed down and sending me a cached version again. I dunno if this is caused by a DDoS, or server maintenance. I appreciate your guys putting up with it though.
