@Tenthrow That "kbin" link is only for kbin.social users. There are other kbin instances such as kglitch.social, fedia.io, karab.in, ...
https://kglitch.social/[email protected] ([email protected]) works for everyone if the community you're linking to isn't on your own instance (which is why it's working for me but not for you; both lemmy and kbin are currently too overzealous at removing the instance part if it's your own instance).
