Unable to connect to Linux vpn server by windows server manager

[sofsasa]

Hi
I install vpn server on a Vps that is Ubuntu 20.
After all is done , I enable and start the server.
In server status it shows Active.
Also I enable IP forwarding .
And I can open https://myip:5555 , and it shows that server is active.
UFW is disabled , but I try commands to open ports as like 443,5555,....

When I try to connect by windows server manager to my VPN SERVER . I received an error that check your host and port address . But everything is right.

Who can help me?
Thanks

Yeah, everything sounds right. What happens when you try to use Windows SE client? Enter any hub/user, it should connect and show an error about hub/user.

Hi
I try to connect with Windows Server manager .
After I set , host name to my Vps ip , port to 443, direct connection and server password .

It will not connect and say check your host name address and port.

I am confused.!
