Takes a minute to start

What happened?

The library takes a lot of time to start.

Consider the following script:

import ngrok from '@ngrok/ngrok';

ngrok.consoleLog('TRACE');

try {

  const listener = await ngrok.forward({
    addr: '8080',
    authtoken: '…',
  });

  console.log(listener.url());

} catch (error) {

  console.error(error);

}

I'm getting the following log output:

DEBUG log - add_parsable_certificates processed 1 valid and 0 invalid certs

(HANGS HERE FOR A LONG TIME)

I'm running it under Linux. The ngrok binary (installed from apt) works fine if I use it directly.

What could be the reason for this? Thank you.

Okay, the fact that it's closing is caused by the script stopping execution. Don't know why the library is not keeping the process running, but this is yet another story.

I'm more concerned with the fact that it takes a whole minute to start. The ngrok binary starts in a second. Would really appreciate some tips.
