[NEED HELP] Server dont appear in server browser

Good day!

I have an issue with appearance of my server in global server browser. My home server don't appear in list. I tried to restart server several times, double checked config, tryed to change settings of my home firewall. Last time i make a traffic dump and saw that my server actually making heartbeats to three master servers: 207.55.114.154, 107.161.23.68, 92.62.40.73 every 120 seconds:


I see that 107.161.23.68 and 92.62.40.73 sent to server "getinfo" messages and my server replies them with server info:


Only 207.55.114.154 don't sent "getinfo" messages:


I cant understand why my server don't appear in server browser if my server replies to "getinfo" messages. Is it because 207.55.114.154 dont replies to heartbeats?

And i must mention that connection to server with "manual" IP input to my external Internet address 46.151.26.194:26000 works fine. I mean NAT and firewalls are configured for UDP/26000 external connection.

Please help!

Kind regards,
