I'm running the newest MCA for version 1.7.10, and I go to get on the server and it says "Can't connect to server" is the server down? This has been going on for about a week now.

"the server"? Which one are you talking about?

The Official MCA Server

I was able to get on it until about a week ago. I don't know what's changed from the last time I was able to log onto the server. I'm running the correct version of the mod, I checked to make sure. The only other mods I'm running are a map and inventory sorting mod, both of which were compatible with the server the last time I was able to log on.

It is currently down for maintenance.
