I'm happy to help you troubleshoot the issue.

Based on the information you provided, it seems like you've set up Cloudflare to proxy requests from your domain (printyourowndunhamid.comprintyourowndunhamid.com) to your Raspberry Pi's localhost (localhost:5000localhost:5000). However, you're getting an HTTP 404 error when accessing your website.

To help you resolve this issue, I'll need to ask a few questions and provide some guidance.

Can you confirm that your Flask app is running and accessible on localhost:5000localhost:5000 when you access it directly from your Raspberry Pi (without going through Cloudflare)?
Have you configured Cloudflare to use the correct protocol (HTTP or HTTPS) for your Flask app? You can check this in the Cloudflare dashboard under the "SSL/TLS" tab.
Are you using any specific Cloudflare features, such as Page Rules or Workers, that might be interfering with the request?
Can you provide more details about your Cloudflare configuration, such as the DNS settings and the proxy settings for your domain?

Additionally, I'd like to suggest some troubleshooting steps:

Check the Cloudflare logs to see if there are any errors or warnings related to your domain or requests.
Verify that your Flask app is listening on the correct port (5000) and that there are no firewall rules blocking incoming requests.
Try accessing your website using the curlcurl command from your Raspberry Pi to see if you can reach your Flask app directly.

Please provide more information about your setup and configuration, and I'll do my best to help you resolve the issue.

I think tunnel is not properly connected to your Raspberry Pi

Remotely-managed tunnels run as a service on your OS. You can modify the Cloudflare Tunnel service with one or more general-purpose tunnel parameters.
