I cant enter the server :( [HELP]

Hola, soy nuevo en este servidor y no puedo iniciar sesión en el servidor:
Cuando entro en el IP funciona bien y estoy dentro, pero a la hora de seleccionar el vestíbulo me sale este error:
Excepción interna: java.ioException: Se ha anulado una conexión establecida por el software en su equipo host

Hi, I'm new to this server and I can not log in to the server: When I enter the IP works well and I am inside, but when selecting the lobby I get this error: Internal exception: java.ioException: A connection established by the software on your host computer has been aborted

 

Hi @Antolito181

Are you using a legitimate version of MineCraft and running the latest update of 1.11.2? Has this error been resolved since Sunday?

I do not know what I've done to my computer but it lets me play, thanks anyway
