I'm trying to create a modded server with a modpack but ther server stops when i try to join

This modpack seems to be working in most cases. We want to give our users as many choices as we can, even if a modpack might not work some of the time. We monitor our systems and remove modpacks that don't work in most cases, but there's no way for us to guarantee that a modpack will always work with our limited resources.

You might have to use a different modpack or check out our paid host exaroton: https://exaroton.com/
