Hello there.
There are some limitations in running dedicated server behind the NAT(Router).
At first, try to change port of dedicated server to 27000 for example, windows may have a bunch of hidden limitations.
And second, you have to enable NAT#Loopback on your router(but most of home routers dont have such feature) to make server available in the server list, but in most cases you`ll cant find your server in a servers list because it have to have static(dedicated) IP to work properly.
ps. after changing port of server, you can try to reach it with console(~ or shift+ecs) command "connect 127.0.0.1:<port>"
