I'm trying to upload my server to PlanetMinecraft and I don't really know what port means next to the server ip. I've filled out all the other things like name, server ip, description and all that. But I don't know what port means. I've searched up videos on how to upload aternos servers onto PMC but I'm not finding anything. I saw in another post that someone said "The servers are meant to be private for friends, not public." I'm trying to make it for my friends, and requiting new members of the Kaleidian Games server/YouTube team.
