Cloudflare Tunnels configured with config file ingress entries can address the “hello_world” service.
There is no option in Zero Trust>Access>Tunnels> … >Public Hostname option to select this service.
Same here…i noticed that its available via the manual / .yml config method but using the GUI doesnt give a service type drop down = hello_world which is also in the documentation.
