Sobre estas guías
Los servidores de juego suelen decirte qué va mal, pero con las palabras de lo que se ha roto: una traza de Java, un mensaje de autenticación de Steam, una línea en un archivo de registro. Las guías de aquí están organizadas por el mensaje que ves en pantalla, así que puedes buscar el texto que tienes delante y llegar a la causa en lugar de a una lista de cosas que probar.
Cada una explica qué significa de verdad el error, de qué lado viene (tu servidor, tu propia conexión o los servicios del juego) y la forma más rápida de quitarlo de encima. Si tu mensaje no está aquí, la guía de registros de Conceptos básicos de hosting te enseña a encontrar el error real detrás de uno genérico, y nuestro equipo leerá un registro contigo en Discord.
