Not a problem I've had with any other server. After I click on 'Accept Invite' (from your links to the discord server) the 'accept' pop-up disappears and the rest of the page remains blank. I'm not redirected to the server. Also on visiting discord I don't see the server listed.
Have you set the invite to a max number of invites which has now been exceeded? COuld you send me a fresh invite?
