Related to shopify app Error refused to connect.

[areesha]

I am facing an issue that wasn't occurring before but is now happening. When using the Shopify CLI, I'm getting the error message 'alphabetical-liability-invite-artists.trycloudflare.com refused to connect.' Additionally, in the console, I'm seeing the error 'Error forwarding web request: Error: connect ECONNREFUSED ::1:49643.'

I have checked the port, and it's free. Previously, the issue was due to the port, but now I'm not sure why it's causing a problem. Please, could you kindly assist in resolving this issue as soon as possible? My work is being delayed because of this. Thank you for your cooperation

Could I get a little more info on this issue? What are you doing with the Shopify CLI when you get this error?

I'm developing a Shopify app, and I'm encountering an issue. I'm working on Remix.

I get this error while running the command "npm run dev"

Here are a few general troubleshooting steps you can consider:

1. Ensure that your Shopify CLI is updated to the latest version.
2. Try logging out and then logging back in using the Shopify CLI to refresh your authentication.
3. Check if your development environment meets all the necessary requirements for the Shopify CLI.
4. If the issue started after updating to a new version, look for any known issues in the release notes or consider temporarily downgrading to a previous stable version if feasible.

Given the variability of these issues, if the problem persists, I would recommend reaching out to Shopify support

I would also try running the command "npm run dev --reset" to reset the connection. Make sure when you reconnect that you choose yes to update URLs.

Just check if there is any error in your shopify app like a wrong import or even a small extra character inserted by mistake in your code.
This error will be shown in the console also before you encounter this error. 
After fixing the error, restart the app, it will work fine!
