Getting 502 Bad Gateway error with ngrok when I use https localhost url in a Node App

I'm developing a Node App. I need https for receiving callback URLs from 3rd party Apps. So I added SSL certificate.

ngrok works only with http URL (http://localhost:3000).

I'm using the command ngrok http 3000. But when I access ngrok https URL, I'm getting 502 Bad Gateway error in browser.

How do I make ngrok work with https://localhost:3000 URL.

ngrok tls 3000? – hlfrmn
@hlfrmn Looks like it's available only with a paid plan. Could you suggest any other alternatives? – Anirudh
I tried ngrok before, and then switched to serveo.net, it's free, no installation and you can impose a subdomain so that you never change the url you're using for development, check it out – Tourki
@Anirudh did you check my answer? Does it work for you? – ffeast

If you are using for signup or login with google/facebook then I can suggest you another way. You can use 

https://tolocalhost.com/

configure how it should redirect a callback to your localhost. This is only for development purposes.

ngrok can itself provide https support - this is one of its major use cases (at least for me) so you don't need to create any ssl certificates

Step-by-step guide

Here's a simple testing file:

$ cat t.html 
<body>
    <h1>test</h1>
</body>

Bringing it up a simple http server on localhost:

python -m SimpleHTTPServer 7070

Running ngrok

$ ngrok http 7070
