Not banned from the Space Station Server, I checked.
Tried reinstalling Byond, trying stable and beta versions, and checking firewall.
Any Idea how to fix?
"Access Denied" is the message you get when you're banned by the host of the game.

This means that you're not banned through in-game means, you're banned from the host's device. This could be a faulty sticky ban.

You're going to have to take it up with the SS13 server that you're banned from and see if they can help you. There's fundamentally nothing anyone on BYOND, Lummox included, can do.
