... 15 more keep in mind this SUDDENLY showed up, and wasnt there until i had used my server for a bit. now tough, it happends all the time. it might be because of grief alert

 

Minecraft problem we think, can't do anything to took to long to log in. For the other error, update McMMO

 

update McMMO.
And is there any plugin on your server named skills, or written by nossr50? (nossr50@gmail) if so, update it too.

 

This excact thing is happening to me except in the console it is simply saying "Disconnecting [ip-adress], Took too long to log in!" or it says "[ip-adress] lost connections/" Hmm, I wonder what it is...

 

Minecraft.net is on it.

 

Good, wait..... How do you know this.......?

 

I follow the Mojang team on Twitter. Very informative
You should too!

 

Just FYI, you also get this error when your server is behind the revision of your clients. So if you had a typo when you downloaded the new bukkit image, and are still running the previous version, you will also see the 'Took too long to log in' error.

If you change your server.properties entry from "online-mode=true" to "online-mode=false" and restart, and still have the issue, then the problem is on your server, not mojangs. (Be sure to set it back after this test.)
