I've been running a server for about 3 months, and all of a sudden it says "Failed to verify username: session authentication server unavailable" My PS3, and my wireless mouse also stopped working at the exact same time. I don't know if these problems are related, but I just thought I'd let you know. I also added the Jail plugin before the problem started, but I don't see how that would be a problem.
Usually it means minecraft's authentication server is down. You can bypass it temporarily by setting online mode to "false" in server properties, but that opens a major security hole.
Really you can't have offline mode for bukkit now? How am i gonna test my plugins D: TnT Like I need it for testing playerlogger, command water needs at least 2 people, AdvIpLog needs loads of users, D:
I agree with Blocking Offline Mode, I know many use it for testing but people use it to bypass buying the game and supporting Mojang
Offline mode works just fine. So very incorrect. There is no issue with setting offline mode in any CraftBukkit released. Locked. You will get no support for setting your server to offline mode.
