I can`t use Nodes US East Vultr1 and Vultr2 (Miami)

Hello.
I reported this problem earlier and got the reply to check http://docs.mudfish.net/en/docs/mudfish-troubleshooting/basic-func/

All of the below were using the Full VPN mode. I don’t have this problem using other nodes from US East. I completely disabled the Windows Firewall and don’t use another one.

The Program Core log is:

I can’t open https://myip.mudfish.net/ using the Full VPN in a browser mode but I can ping it as it shows:

:frowning: Ooops… Then try to change Connection Protocols from UDP to TCP. This issue could be MTU (Maximum Transmission Unit) issue.
