Troubles with Online Lobby in Demo Platformer Game

[danilamaster]

Try to launch Demo Project and implement online lobby with GMnet Punch.

My config:
self.gmversionpick=1; and uncomment string 58 in https://github.com/Parakoopa/GMnet-ENGINE/blob/master/GMnetENGINE.gmx/scripts/htme_serverStart.gml
self.use_udphp = true;
self.udphp_master_ip = my dedicated server IP
self.gamename = my game name string
all other are defaults

Successfully set up dedicated server on Digitalocean.
This is status of 6510 port on dedicated server

netstat -tulnp | grep 6510
tcp6 0 0 :::6510 :::* LISTEN 101005/java
udp6 0 0 :::6510 :::* 101005/java

When I start game server in game menu with N-key dedicated server cosole always responce with 2 lines
Register UDP Server with port 6510 and TCP server with random port
for example
1/30/21, 11:42 AM : 37.XXX.XX.193:6510 - UDP - Server registered!
1/30/21, 11:42 AM : 37.XXX.XX.193:63967 | TCP | Server registered!
or
1/30/21, 11:23 AM : 37.XXX.XX.193:6510 - UDP - Server registered!
1/30/21, 11:23 AM : 37.XXX.XX.193:63175 | TCP | Server registered!

Server version of the demo game display debug overlay and info about synced player

Now when I open online lobby game it successfully display server data on first slot of lobby list
When I mouse click on it dedicated server responce 3 lines
1/30/21, 11:42 AM : 37.XXX.XX.193:56811 - UDP - Client registered!
1/30/21, 11:42 AM : 37.XXX.XX.193:63980 | TCP | Client <-> 37.113.90.193 -> Connecting...
1/30/21, 11:42 AM : 37.XXX.XX.193:63980 | TCP | Client <-> 37.113.90.193 -> CONNECTED!
I suggest all ports are my local ports as a client
They are always different from connection to connection
for example
1/30/21, 11:47 AM : 37.XXX.XX.193:65170 - UDP - Client registered!
1/30/21, 11:47 AM : 37.XXX.XX.193:64146 | TCP | Client <-> 37.113.90.193 -> Connecting...
1/30/21, 11:47 AM : 37.XXX.XX.193:64146 | TCP | Client <-> 37.113.90.193 -> CONNECTED!

After that I hope client and server will establish connection but this is not happen.
Client just restart game and go to main menu.

Some log messages from GMS2 IDE

Looks like 6510 port did not responce on dedicated server and connection can't be established.

What I have to do to force demo game use online lobby?

I'm in the same boat.. curious why this isn't working in htme_obj_waitforclient

///Check if client is connected
if (htme_clientIsConnected()) {
    room_goto(htme_rom_demo);
}
if (htme_clientConnectionFailed()) {
    htme_error_message_handler("Connection with server failed, it may be full!");
    htme_clientStop();
    room_goto(htme_rom_menu);
}

it never confirms that the clientIsConnected... so I'm wondering if the server java is actually working correctly.
