The default actions in Eaglercraft if no :port is presented when connecting to some server is to use port eighty, not port 25565. This can be so the game’s multiplayer connections inside of a generation setting don't default to the port that is certainly presently blocked by any firewalls. https://www.reddit.com/user/ukIsmine/comments/11suiwb/a_comprehensive_guide_to_eaglercraft_minecraft/
