I did everything correctly with the configuration and when I access my domain, a black background appears with the following phrase: 
Something went wrong
Which app did you tunnel? Is the tunnel healthy in the Cloudflare dashboard?
the humbrel os home page. I want to access.
Ok. Is the tunnel healthy in the Cloudflare dashboard and is this taken into account in the umbrel cloudflare app?
it should look something like this in Cloudflare:
and in Umbrel:
Yes
Have you tried using umbrel instead of umbrel.local? Or try using the IP.
I’m having the exact same issue. umbrel.local seems like the right URL, since everything else fails to connect at all.
update: Ok I found a (first-layer) solution. It’s Cloudflare SSL-TLS config - it needs to be changed to “Flexible”.
https://dash.cloudflare.com/{cloudflare_id}/{domain}/ssl-tls/configuration
update: it seems now it only works in “Off” mode. “Flexible” worked because I had the site cached, until it didn’t work anymore. Having encryption “Off” for my entire domain is really bad because I use it for a lot of things. Still looking for better solution. I might have to give up on cf tunnels and use wireguard + custom firewall.
I really hope https support is on the roadmap.
I am having the same issue, the lack of HTTPS support is insane, maybe one day questioning a refund at this point hours wasted hours
