I started a Server For 5 players in vanilla 1.14.4 all my 4 friends could login but i couldn't,the error said :
Internal Exception: io.netty.handler.codec.DecoderException: java.io.IOException: Bad packet id 26
but in the console :
lost connection: Internal Exception: io.netty.handler.codec.DecoderException: The received string length is longer than maximum allowed (17 > 16)
i Checked many forums and other people had problems with their bukkit or spiggot (i don't even know what these are) they had problems with citizen mods and too long nicknames (wich isn't my case since my nickname is shorter than 16 characters and i don't even have mods since i'm in vanilla) i tried changing the server and my version to 1.7.10 to try other versions but still the same problem, people also had problems with location logout but since i never logged in this can't be the case so i don't know any way to solve the problem.
Do you ?
