Option #2:
You haven't portforwarded ports 80, 30800 and 30810.
Solution:
CMD -> ipconfig/all -> Scroll up till you find something like:
Standardgateway. . . . . . . . . : 192.168.123.123,
-> Go there in your browser -> log in -> search games/applications or something with portforwarding -> Local IP: IPv4-address. . . . . . . . . . . . : 192.168.123.115, something like that -> ports: 30800, 80, 30810.
Option #3:
Your firewall is on.
Add ports 30800, 80 and 30810 to the exception list or shut down your firewall (Not safe)
