Able to join server, but times out every time.

I have never had any problems with my server. The only plugins i have are: gwarp, ultimate economy, and Chestlock GUI on spigot. I have tried joining on the dynamic ip, same issue. I can join but i get kicked out within 20 seconds. I didnt find any issues in the log. thank you

Roman No, the problem persits on vanilla. I also get the problem "connection was forcebly closed by the remote host" sometimes

Roman I submitted a ticket with the requested info 2 weeks ago, but i recieved no response and the problem persists. Please help.

Roman im so sorry i havent seen it, it was an automated response with this link. I changed my dns server to the google public dns, conected with the dyn ip and no change. I responded to the ticket email but nothing seems to have happened. Im sorry but i dont know what to do.
