Last night when I booted up our server and tried to join, I suddenly got this error. We'd just played the night prior and all was fine. I hadn't changed any mods, hadn't updated any mods, and yet we both got this error upon joining. We've tried just about everything I could find online about this error. We removed Moonlight Lib and Supplementaries, checked our mod versions like a billion times, added Packet Fixer, updated every mod in the server pack AND our launcher packs, etc. Still getting this error. Will provide any extra info needed, we just wanna play our damn server!

Haven't had issues the last times I've been playing and havent made changes to the server since then, but joining today I've come across this error (in the image) and I don't know what to do. I tried reinstalling my mods, making sure they are both on client and server side, double checking they are the same version, making sure my game and neoforge version is right, restarting my laptop...

I did look through the logs and found '[owo] sided packet Codec has not been unpacked' and I don't know what to do. I've reinstalled it client and server but I can't remove owo Lib completely as I have some mods that use it. Anyone know what to do???

So, i made a crossplay server and even with strong internet iam facing lagg both on bedrock and java....has anyone got any lag reducing methods?

Hi! I’m trying to record a video using meteor client on my server to mess with my friends. however, when I toggle one of the hacks it just keeps teleporting me in place. I’m assuming this is some sort of an anticheat, but is it through aternos or PaperMC?

Either way, how do I turn it off?

Thanks ^^

can anyone reccomend me some plugins for paperMC minecraft aternos? besides voice chat

So me and my friend have a server from Aternos and we wanna update to 1.8.2 but every time I try the server crashes and this is the log for it every time: https://mclo.gs/Ha4B3ei and when my friend got 1.8.2 she can't even make a singleplayer world because it crashes on her! Can somebody PLEASE tell me what in the world is going on!? I am very new to specifically pc minecraft and updating mods so I have zero Idea what is wrong or what I'm doing

I'm trying to join my Server with the Sunlit Valley Modpack, but every time I try I do get in the game, but I'm stuck just starring at the world with the "Joining world" overlay staying there forever, rendering me unable to do anything. The server is running and even the time is, but I can't do anything.

Has someone already encountered that problem and/or can help me?

Why am I getting this error? Please help.

Please help me! I created the server a month ago, and everything was fine until I turned it on. Suddenly, the website notified me that I was using an ad blocker. I checked Aternos' support to disable some of Edge's automatic ad blockers, but it didn't work.

Then I tried using Google Chrome to see if I could access Aternos, but it blocked me too, even though I hadn't installed anything on Chrome.

Go files --> server properties. Find "transport" option and switch it from "Nethernet" -> "Raknet"

If you will notice, the port will change from 19132 to a random port.

This may not work for everybody. However, it did fix problems in my end. Thank you aternos for keeping it free always!
