Bug: Issue with URL Generation in nport using API method

[gitSambhal]

Hi @tuanngocptn Found a bug when using the package in API

The script hangs when using nport.link without server subdomain. Additionally, the generated URL format is incorrect.

const socketTunnel = require('nport/lib/api');

const main = () => {

  // The script just hangs on using the nport.link without the subdomain
  // const server = 'https://nport.link'; 

  const server = 'https://server.nport.link';
  const subDomain = 'my-subdomain';
  const port = 3000;

  socketTunnel
    .connect(server, subDomain, port)
    .then((url) => {
    // The output url is https://my-subdomain.server.nport.link and it doesn't work
    // but accessing the url https://my-subdomain.nport.link works.
    // so the output should be correct working url.
      console.log('🚀 ~ .then ~ url:', url);  // Incorrect URL format
    })
    .catch((err) => {
      console.error(err);
    });
};

main();

Expected Behavior:
The correct URL https://my-subdomain.nport.link should be returned.

Actual Behavior:
The returned URL is https://my-subdomain.server.nport.link, which doesn’t work. Accessing https://my-subdomain.nport.link works fine.

Environment:
• Version of nport: 1.0.6
• Node.js version: 20.15.0
• OS: Mac

Additional Context:
• The script hangs when nport.link is used without a subdomain in server.
