Error when someone joins

Discussion in 'Bugs & Feature Requests' started by Minevid, Mar 1, 2013.

  1. Hello everyone,

    I've had this error in my console a lot when players join.
    Could someone tell me what the problem is? :

    I don't think that's the entire error - can you maybe check to see if there's more?
  3. It is the full error.. :s

    This is the same error but from my server log instead of my console (backwards and another player):

    2013-02-11 18:51:11 [INFO] Disconnecting maycowte [/]: internal server error

    Hmm, can you give me a list of all of your plugins?
  5. Puremin0rez


    Hmm, the only plugin(s) i see that could cause something like that on login is possibly ProtocolLib, GeoIPTools and xAuth.

    What build of Spigot are you on?

    I'm running the latest dev as of this post with ProtocolLib and no errors - which means we can rule that out.

    xAuth has been giving people some problems with Spigot recently, so it could be that (you may need to update it or something)

    Never heard of GeoIPTools, but I understand what it probably does.

    No apparent cause sadly, good luck
  6. Actually I am running a Dutch server so I am blocking all the other countries and proxies with GeoIPTools and Easyban.

    I'll update my ProtocolLib and xAuth.

    Just a tip:

    You can kill two birds with one stone with my plugin (AntiBot), it has GeoIP built in and also has country banning as well (whitelist and blacklist modes). If you use Easyban to ban other proxies and countries and prefer to do that instead, that is fine.

    A plugin might be listening to the PlayerLoginEvent and doing something to a player before they're actually on the server, that's all I can think of.
  9. I'm never going to use antibot again, sorry.
    I liked the idea but it didn't work out pretty well for me :p
  10. What plugin might cause this error?
  11. YoFuzzy3


    Any plugin that uses the event. If you do /timings merged and check the file it outputs you'll find the PlayerLoginEvent mentioned under the plugins that use it.
  12. When someone on my server enters the end from a ordinary the end portal, from corner to corner, the person will get stuck in a loop and the server will kick him every time tries to log in and the server log throwing out this error message that you have.

    To solve it i need to edit the position of the person to another place with NBTedit.

    I dont think its a plugin cusing this.
