It worked fine, thanks. So here is the server debug log file. https://gist.github.com/WiraxET/5df763cfbb7ac92ae9de7aac3066e234 Thanks for your replies and for your wait.

I cannot upload to Github gists because the file is too large (approx. 9MB) and the text cannot be uploaded, the site making an error (timed out). So is there any solution ? Thanks again.

I have a big problem... I can't post my logs on any of the websites you mentioned (also on Github gists), how can I do to give you my debug.log file ? It's quite a problem. Thanks for your reply.

Sorry for this, but I didn't have any reply and I can't solve this problem by myself, because I don't know why the server does this. So, if someone can help me, it would be nice. Thanks ^^

Hi, I created a Minecraft Forge server in 1.12.2 with the latest version of it, with a collection of mods made by myself, I sent the mods and the configuration files to my friends, but the only person that can connect to the server is myself. They have the same mods in the same version as mine, and the server also has same configs and mods as mine (except from JEI, HWYLA, Optifine and other client-side mods). My friends' MC clients don't show any error when they try to connect, but the server shows an error : [12:45:46] [User Authenticator #6/INFO] [minecraft/NetHandlerLoginServer]: UUID of player ****** is af163543-8c07-4859-b4c9-cfaaef594315 [12:45:46] [Server thread/INFO] [minecraft/NetHandlerPlayServer]: ****** lost connection: Internal Exception: io.netty.handler.codec.EncoderException: java.io.IOException: Can't serialize unregistered packet If I could have a solution to this problem, it would be nice. Thanks in advance for the help you should give.
