I have the modpack and every single mod of it in the modfolder why can't I join anyway
Maybe your forge or Java version is not up to date and you need to update it
Do I have to use the latest version from forge?
Yes it depends on which version the server has
Maybe you're just simply not on the whitelist
Is a public server
Isn't there anywhere
Check out a Youtube video
So I know that it is on 1.16.5 if you mean the version but I know which forge version
Oh wow I should really read the answer to the question again before I write an answer to your comment.
