Host node.js script to any hosting like heroku

[Pepe1221]

i cant upload your code to heroku or any other similar node.js hostings, i have try a few but i always get the same error, so i guess you cant host it

another issue, people cant connect to my minimap using my public IP:34343
port is open btw, so it should be fine, i cant also connect using my own public IP, am i missing something?, i tried to leave firewall off but still issue persists
