However, few days ago, my country's internet connection via the Asia Pacific Gateway (APG) undersea cable broke down, and my ping with Radmin VPN (inside Hola VPN) rises over 300ms now. So I found another solution - Cloudflare Warp. It gives me a decent ping (around 120-180ms). But there's a problem, neither I nor my friends can't ping each others's IP address through CMD. It always responds "Request timed out.", although in the Radmin VPN UI it still shows each others's ping.
I've disabled my firewall and antivirus aswell. I've also tried to ping these 3 of RadminVPN's ip address (51.89.192.55, 51.89.173.95, 147.135.70.219) and here's the result https://imgur.com/gallery/tuCbVmI.
Open Windows command line (press Win + R) and type
cmd
and press enter.
Type
ping 147.135.1.122
ping 51.77.117.69
ping 147.135.36.105
wait till the end of each command, make a screenshot and send it.
1. Stop the radmin vpn service (Control Panel \ All Control Panel Items \ Administrative Tools \ Service), find radmin right-click and sel ect stop.
Run the cmd as administrator and enter:

2. You can also try this, if there is a problem with DNS cache of your internet provider. Here's the steps for changing DNS to Google. It solves the problem with always connecting state. https://www.howtogeek.com/164981/how-to-switch-to-opendns-or-google-dns-to-speed-up-web-browsing/
3. If you use proxy, you need to set it up in Radmin VPN - System - Settings - Advanced.
4. Turn off firewall and antivitus for some time to complete connection or registration.
5. You also need to make sure that port range 17000-18000 is open. Here you can read about opening ports https://www.windowscentral.com/how-open-port-windows-firewall
6. Make sure that Radmin VPN is not blocked in your country and by your local provider.
7. Open Windows Command Line and run the following:
netsh int ipv6 set teredo enterpriseclient
netsh interface teredo set state servername=win1910.ipv6.microsoft.com
