Umbrel and CloudFlare Tunnels

I have a Raspberry Pi 4 running Umbrel OS and on it i have the Whoogle search engine. I would like to point a subdomain to this application, but it doesn’t seem to work. I have set the tunnel. The tunnel status is Healthy. The application is available internally at http://192.168.68.72:6420/ but the tunneled subdomain connection says:

This site can’t be reached

mydomainname.com took too long to respond.

Try:

ERR_CONNECTION_TIMED_OUT

I would check the DNS record of the tunnel to make sure it points correctly.

were you able to get it working with umbrel?
