If going to https://api.minehut.com shows something like you're blocked or a cloudflare error, then create a support ticket here as you may have gotten blocked from Minehut's API and they can fix that for you. If you just see Cannot GET /, then that is normal and that's not an issue.
If none of those work, create your own separate post requesting further help since this post is getting locked for necroposting.
