We are currently using the cloudflare service for our customers who have their own domain pointing to our SAAS, the customers point to cloudflare where the valid SSL certificate is generated, and from cloudflare attacks the application on railway.

The problem is how from cloudflare can reach railway in a (Full) way that is to say by https between servers and that the certificate in railway is self-signed.

Is there any way to achieve this without having to configure the domains in railway? In fly.io it is possible to set this so that any domain that points resolves with a signed certificate.
