502 Bad Gateway using ngrok – Shopify

I am trying to use ngrok to create a dev shopify app. I had it working for a short time, but now i keep getting the error message.

enter image description here

The connection to https://da003848.ngrok.io was successfully tunneled to your ngrok client, but the client failed to establish a connection to the local address localhost:3000.

I am alo seeing the 502 error below;

    You are showing two different ngrok tunnels.

    The console is tunneling to da003848 while the Shopify app points to fb393d38.

    You need to use ngrok premium to set a static domain tunnel or you need to update your Shopify App url each time you start your ngrok service since it will change each time since your are on a free plan.

    So the solution at the moment is to update your App URLs from the Shopify partner dashboard with the proper tunneling that you’ve started now.

    when your terminal in on then ngrok will return the same URL but when you restart ngrok it will create a VPN with a new URL. You can also signup then it will work permanently until your system is ON.
