    I have a modded aternos server, me and one of my friends are able to join just fine, but everyone else keeps getting this error:


    [13Dec2021 22:17:01.232] [User Authenticator #14/INFO] [net.minecraft.network.login.ServerLoginNetHandler/]: UUID of player AWSditto is 86905634-66ca-49ec-97a0-feaa9e1f968c

    [13Dec2021 22:17:03.052] [Server thread/INFO [net.minecraft.network.login.ServerLoginNetHandler/]: com.mojang.authlib.GameProfile@4d0442c6[id=86905634-66ca-49ec-97a0-feaa9e1f968c,name=AWSditto,properties={textures=[com.mojang.authlib.properties.Property@60907e0a]},legacy=false] (/130.113.109.215:58279) lost connection: Disconnected


    there are no other logs related to the disconnects but they do occur each instance they try to join.


    We have tried everything we can find on similar threads; double checking mods folders for inconsistencies/different versions/incompatibilities, switching on and off of cracked mode, checking forge versions. we all copied the mod pack from the same google drive folder. The problem is happening both for people with real mc accounts and using cracked accounts. Also the same people having this problem joined with no problem just yesterday, but we updated the modpack since then. I do not know what else to try.

    The provided log messages are not really errors.


    Can you please share the full log?

    Also, which error message is displayed on the players' screen when they get disconnected?

    The error message on their screen reads


    Failed to connect to server


    Failed to synchronize registry data from server, closing connection


    As for the rest of the logs are you asking for the server startup logs? the only logs I see are the disconnects mentioned above, console logs like advancement notifications and console commands and lag notifications: [14Dec2021 20:17:27.940] [Server thread/WARN] [cgm/]: shnozzzz(94fc5c9b-ed95-3370-b2c3-78bd7fd6aa81) tried to fire before cooldown finished or server is lagging? Remaining milliseconds: 63

    I can't see any connection attempt to the servers in the client log. Tell your friend to try connecting to the server and once he/she gets the error close Minecraft and then share the client log
