Need a static url (ngrok changes urls). Cloudflared Error.

[AnswerBook]

I learned that creating Script tags means that you need a static url, or update the new ngrok host url on all script tags every single render. The Shopify CLI does not support a custom domain for ngrok (as far as I know) and so I looked into a Cloudflared tunnel. 

I got the Cloudflared tunnel setup and working with a domain I own and pointed it to Cloudflared. Now I have a Cloudflared tunnel setup and running with the command:

cloudflared tunnel run --url http://localhost:7000 

In which I have already setup the tunnelID and configuration. I can run a test, cloudflared tunnel info <UUID> , and it verifies my tunnel is running. 

I now go into my app to run the code specified in the readme that comes with the CLI when you create the app. 

And run/test the following codes:

npm run dev --tunnel-url http://localhost:7000

npm run dev --tunnel-url https://localhost:7000

npm run dev --tunnel-url http://www.myowneddomain.com:7000

npm run dev --tunnel-url http://www.myowneddomain.cloudflared.com:7000

All giving me the same error:

I have also given it a try to put in different urls into the URL setup for my app in the partner Dashboard. I'm not sure if this has anything to do with the error but I figured it was worth a try. 

This screenshot can be found by clicking on your app and tabbing down to "App Setup" on the left menu. 

Has anyone successfully setup Cloudflared? Has anyone successfully setup a static url for their app regardless? Should I just go ahead and get a Heroku account and run my app? I am struggling to run locally without the CLI because there are no react-scripts / npm functions to run the app without the CLI. Shopify has a configuration unknown to me where react-scripts points to the public folder when it needs to point to the pages folder. Has anyone had issues with these things? Please help! Thank you.

Use CloudFlare tunnel, it is relatively easy (yeah that is CloudFlared).

Open Zero Trust

Go to Access, then tunnels.

For the public hostname config, choose a subdomain and one of you CloudFlare (proxied) domains, then set the service to http, your localhost (or your docker IP) + port.

Save it all, run the docker container they provide you with.

That should work.

Another, maybe simpler way would be to just forward a port on your router and point a sub domain to your public IP address, though I'd go for the tunnel.

Sorry to bring this up again but what do we use for the --tunnel-url flag in Shopify CLI?
In ZeroTrust my tunnel is set up this way:

1. Public hostname: subdomain.mydomain.com
2. Service: https://localhost:8001

My shopify cli command is:

npm run dev -- --reset --verbose --tunnel-url https://subdomain.mydomain.com

It says error: invalid tunnel-url

So I tried 
npm run dev -- --reset --verbose --tunnel-url https://subdomain.mydomain.com:8001

It completes without errors, but it still doesn't work. I cant install the app on any store.

Unfortunately Shopify CLI 3.44.1 does not set up the app on any store, even though a store is chosen. It also doesn't set up any tunnel, even ngrok, which is why I am messing with Cloudflared.
