Virtual hub name setting value for vpngate.net servers

[Roman]

Hi everyone!

I'm using one of the servers from https://www.vpngate.net/en/ list. And I'm trying to connect to the server using SoftEther VPN client. As prescribed I'm using the server's IP address, 'vpn' as username and password. But what should I enter into 'Virtual hub name' setting? I've attached a screenshot of the setting window of SoftEther VPN client and highlighted setting I'm asking about.
Without filled-in 'Virtual hub name' setting OK button even disabled so I should enter something, but cannot find any info what is the default for 'Virtual hub name' for the VPN severs in the vpngate.net list. I tried VPNGATE and DEFAULT with no luck (connection is not established).
Any help, please?

Check "Disable NAT-T" and VPNGATE hub name will appear automatically.

thank you for a quick reply!
I've checked the box but it adds '/tcp' to the server IP address. So, for example, now I have '219.100.37.102/tcp' in the server name text box. Ok, I've added 'VPNGATE' as 'Virtual hub name' setting manualy. But still can't connect to server (the box is checked). I've tried several servers from the vpngate.net list just in case but still get connection can't be established error.

I can connect to one of "VPN Gate Public VPN relay Server" though (I use "Use UDP Protocol (Ethernet over UDP VPN)" option, the other one doesn't work). So I guess in general my SoftEther client and all is ok.

If you have any ideas what I'm doing wrong connecting to a server from vpngate.net list - it's the most appreciated!
Thanks
