I don't see your name in the ban list (also it would be strange if you were banned if you haven't even been in the server. The link seems to work fine for me, and many others have been able to join using the same link recently, so that should be fine. It could be that Discord had some local server issues in your region just as you were trying to join, some adblock, antivirus or other software prevented the invite from appearing properly, or your internet fell out for a minute just as you were trying to join.
You can try this invite link instead, though it's essentially the same one: https://discord.com/invite/didgames
