Serenade

I'm trying to get HyperGTS to work in order to give myself multiple event pokemon, as well as having an easier way to ge tpokemon onto my Pokémon Diamond game rather than trading from game to game (I have My Pokémon ranch on my Wii and I'm OCD like that in wanting to fill it =p) However, it constantly says that Port 80 is being used (when it's not, I've checked this over and over via netstat -a and canyouseeme.org) and I have the DNS server set as my PC's IP address. Any suggestions?
