For help regarding Aternos, we recommend you to visit our support center.
In the logs it says :" [Aternos System/ERROR]: Server was stopped because it took too long to start. Try reducing the load to avoid this in the future."
I'm using java with curseforge modpack named "Chroma Technologies 2"
But before that the server was functioning normally please help. 
That error might mean that the Aternos server took too long to start because of big mods/modpacks, etc.
Maybe the mod you're using (Chroma Technologies 2) is a big mod that Aternos can't handle much.
