[Bug]: No available server when Cloudflare SSL/TLS policy is set to Full, with multiple domains

[clho40]

Error Message and Logs

When deploying a WordPress application with MariaDB on a Coolify instance hosted on a VPS, using a Cloudflare-managed domain (def.com), browsing with SSL set to "Flexible" results in mixed content issues, while setting SSL to "Full" produces a "No available server" error.

Steps to Reproduce

1. Set up a VPS with Coolify.
2. Point two Cloudflare-managed domains (abc.com and def.com) to the VPS IP using A records.
3. Configure the Coolify instance to use http://coolify.abc.com as its domain name.
4. Create a new WordPress with MariaDB application on Coolify.
5. Assign def.com as the domain name for the WordPress resource.
6. Set Cloudflare SSL mode for def.com to "Flexible" and browse the site.
7. Observed result: The site loads, but some scripts are served over HTTP, causing mixed content issues.
8. Change Cloudflare SSL mode for def.com to "Full" and browse the site.
9. Observed result: "No available server" error.
