I'm developing an app that uses Ngrok for dev. Running ngrok from console works:
ngrok http 3011
shows the "console UI" indicating that the tunnel is up and giving me the url to use.
Now I'm trying to setup things so that developers don't need to copy-paste urls etc. But the very basic usage fails for me:
// prepare-server.ts
import ngrok from 'ngrok'
import config from '../config'
(async () => {
try{
const nwhUrl = await ngrok.connect({ addr: config.serverPort })
console.log(nwhUrl)
} catch(e) {
console.error('problem with ngrok:', e)
}
})()
Gives me (when run as ts-node src/prepare-server.ts):
problem with ngrok: NgrokClientError:

Note the 503 Service Unavailable code. How so if the CLI version works?
Any ideas how to debug this? I've also tried this without options (await ngrok.connect()) and the output doesn't change much. And this is an absolutely basic example (see docs), so I can't really do more to simplify the code, looks like something about Ngrok internals... Node package is v4.0.1
from How to debug Ngrok not starting via node module?
