Description:
My friends cant join my server on my laptop unless me! Im not sure what the problem is, because it doesnt give any errors. When someone wants to join it says 'Can't reach server' They are nicely connected with me on Hamachi, and have the right IP... I really need help! When i start the server on my Windows XP desktop it works... :/ This is a laptop btw.

 

Do they also try to join on the same port?
If everything else fails, I suggest port forwarding instead of Hamachi.

 

I may not portforward, so Hamachi is neccesary. And i dont understand 'Do they also try to join on the same port?' You dont need to type a port to join a server, at least i dont need to. I always choose 25565 as port.

Im sure this isnt hamachi's fault, because on my Windows XP desktop it works perfectly... And the desktop also runs Hamachi.

i dont think Bukkit support hamachi. but on the computer thats hosting the server you need to trust then. go into the hamashit window. then, if any users have a yellow/red triangle click it and click the box that appers then theres another yellow/red triangle and click the box that appers then click "trust" as the button. (you might have to do this on the Win. 7 comp too). sorry for bad spelling

 

On my Windows 7 laptop this isnt neccesary, im not sure why. Maybe its a option to put it on or so. But on my computer its all green, as well as on my laptop.

Help is very neccesary! Please help!

well, i have no clue. this seems to be a Hamachi problem as others can join. you'll have to troubleshoot with them. sorry :/ i dont do Hamachi servers. not many people on Bukkit do. And why can't you Port Forward?
