shopify app serve, (ngrok) site cannot be reached

Whenever I run ‘shopify app serve’ command and try going to the ngrok link, my app will appear for .5 seconds and then fail with browser error: ‘site cannot be reached’.

So I can’t really develop.

I can go into my shopify store that has the app for testing and load it in there and develop it in that environment, but any api call goes through the ngrok port so it doesn’t work.

Anyone ran into this before?

Does that command line link ever work or am I supposed to go in to the app through my shopify test store > apps > my app?

Hey Todrick
Did you manage to solve this issue?

I am having the same problem and I have tried everything, since a new environment to a new shopify account / store. Don’t know what to do anymore.
