It means those mods aren’t allowed in that server, and you need to disable them.
Well what mods are they I tried to do that but it didn’t work
Where did you download the modpack from? If the mods don’t match up perfectly then it won’t allow you on the server.
I’ll try redownloading the modpack because I downloaded the server pack the launcher does’t work for me
You have to launch from a launcher for it work correctly…
Honestly try the technic launcher.
That link is for the cc3 modpack, but you’ll need the launcher to run it.
Can you please tell me from where did you got that modpack?
