LÖVE

It seems the problem is coming from my computer, I asked a friend to host a server and it worked
That's really strange

Hairpinning is where a machine on the LAN is able to access another machine on the LAN via the external IP address of the LAN/router (with port forwarding set up on the router to direct requests to the appropriate machine on the LAN).

Sorry, I don't really understood what you said especially what hairpinning is.. but I port forwarded the corrects ports (22122) on my router with UDP and TCP protocols.

It doesn't matter that you portforward, if your router doesn't support that feature, you won't be able to connect from the same network via your external ip, that's how it works. And that's why it works when someone else is hosting the server, because he's now on a different network.

Does it work if you host a server and your friend tries to connect to it?

If so, then it's what Kayle says: you can't connect to your LAN from your LAN via the external IP, because the external IP is only visible from the outside.

If not, the problem must be different (possibly the IP).

No, he can't connect to the server if I host it

Might be a long shot, but if your friend can host it and you can connect, but not vice-versa, check your firewall settings.

I allowed the right port in my Windows firewall but it doesn't seems to work also

I am also having the same problem. I have port forwarded my router. i have allows love2D through firewall but I cannot host whatsoever. Does anyone know the IP we need to use in order to host? Should it be the private IP or the public IP? The Best Results I got with hamachi but when I connect from another network it is too slow and i get disconnected often. Any Idea would be helpful! Thanks!

Generally always the public IP. Private IPs only work on the Local Area Network (LAN), i.e. only for computers connected to your modem/router.
