Myself and 2 friends run an online hosted server. We are running craftbukkit 1.6.1 dev. We are running multi plugins but none were updated just before this issue started.
The server appears offline in people's multiplayer section of the minecraft launcher, however the server is online and if you ignore the message and click join you can get on the server just fine, the main problem with this is that people who don't know to click join whatever it says think we are offline, which we aren't.
Hmmm, interesting, thanks.
I'm still getting the same error, it says offline but I can join fine. Earlier it was removed by minestatus - despite supposedly being up (I checked uptime and it has been running all day) but it is now back up, I've no idea what is causing it still. There's no error when joining the server, it just seems to be a display issue or maybe it's rejecting the ping or something like that.
