Forcibly closed by the remote host etc.

every time me and my cousin joins our modded server few minutes later me or my cousin would get kicked out giving either me or him
-Timed Out
-Forcibly Closed by the remote host
-Disconnected
-(something connection)

My guess is that its our internet connection since the server did not crash or stopped
also upon joining we only have 1 bar (you know when pressing tab it shows the people and green bar something)

Its mostly me who gets kicked out and the worst part is when you get kicked out you cant join back, it either loads then kicked again or either 1 of that 4 i mentioned the only way to get in again is either by random luck that the goddamn server would let me in or either restart the server

i really needed this to be fixed, so if someone can help me that would be great
