I tried to create a Minecraft server to play with my friends, but they can't join. I tried port forwarding and using Hamachi but it keeps saying "Can't Reach Server." I can join perfectly fine, but getting others to join is the problem... I'm using a Mac, if that helps.
check if they are in your hamachi network, if they are make sure you are using the ip4 adress if so then make sure your firewall is down and actually try taking the ip4 adress and putting it in the server.txt document where it says either server adress or server ip. if it is still not working then switch the online mode to its opposite.
