Server problem

[hellllllltomx]

Hello.

I was working with server files and everything were fine. i hosted server on my pc ( not hamachi) and played with friends.

after more than week something went bad. when i run server, everything seems to be fine. works for me perfect. but my friend's seeing CHECK. they can run client normaly, but its on check all the time.

Any solution?


PS:
1.i tried to off firewall
2.i don't want hamachi

Makesure the service type is Operating not Hidden or anything else.
