port is fully opened (both TCP/UDP). Server registers itself with public listing if the config tells it to go public, but the game first marks it as incompatible during the refresh, and then as not accessible.

same server can be seen just fine on localhost, its remote machines that have the problem.

I tried changing server ports to the minecraft port in the unexpected chance that the port might be blocked. I have used this port before. There is no reason whatsoever for it to not be working.

windows firewall is completely turned off, so it is not responsible.

Do you have any ideas on what I should do?
