I recently had a problem with the Multiplayer mod. I try to join 160.251.58.131, but it just kicks me out with the following message:

You have disconnected.

It shows it immediately after I connect to the server

(I can still join 61.82.248.222 though,but nobody joins it)

I cannot find any related problem on Google. Am I banned or something?

(Weird thing I noticed before was my ping increasing as the connection time passes)

Thanks to anyone who answers my question...
