I'm having trouble.

Hello, after much distress and tears, my pal and I have yet to find a solution to this horrible problem. Every single time we try to open the game in our server it either crashes right then, or it'll crash about 2 minutes in. I'm sick and tired of this. This has caused much pain as I am not in a good headspace. Anyway, I've tried both Forge and ATlauncher, which is the one recommended to open mods.

The error message is: Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: incorrect data check

In conclusion, we really need help. This has gone on for about a week. Thank you

Where did you download the serverpack from?

and how is it being hosted

[glad mulch]

I downloaded it from ATlauncher and its being hosted from Bissect

[burnt tangle]

no you need to download the serverpack from curseforge website, not from atlauncher as that is where you play the pack

[glad mulch]

i did at first, that still didn't work:(

i downloaded the server pack from the website just now. I then played the game using atlauncer and its still not working

[burnt tangle]
