[BUG] UI setup does not work correctly using a Cloudflare tunnel

[richardfrost2]

What happened?

When setting up the UI using a Cloudflare tunnel, the setup does not complete. It gives the error "Error
The hostname <bunkerweb.example.net> is already in use.", even if the hostname correctly points to the UI container. The expected behavior is that the setup continues.

How to reproduce?

Have a host with cloudflared installed, and set up a tunnel, "bunkerweb.example.com" (names are examples), resolving to localhost:80. Set up bunkerweb in the yaml file you provide docker-compose so that bunkerweb.example.com goes to the UI container "bw-ui". Launch your container group, and connect to bunkerweb.example.com. Fill out the UI for first time signin, setting REVERSE_PROXY_HOST to what is specified in the docker-config.yml file, REVERSE_PROXY_URL to any value, and server name to bunkerweb.example.com.
