Good afternoon... can someone provide some guidance on getting a cloudflare domain to resolve when using www

content field in your screenshot.cloudflared tool on your home server? I'm guessing it's one of two things:www in the settings for Cloudflare Tunnel (you need both abs and www)abs and www. If you add only abs and then manually add a DNS record for www from the DNS tab it won't work.
abs and www
www is the subdomain in this case. So the leftmost box should have www and the middle one should have pendejo.wtf
* for all subdomains but I wouldn't recommend that unless you have tens of them.
