I have owned Factorio for some time now and have been playing it single player all time, recently my friend got the game and I wanted to play with him.
But every time I host a game a Notice appeares on my screen "Failed to determine external IP address. players might not be able to connect".
I have searched for solutions and found some other ppl having a simmiliar problem but there solutions didn't work for me
