403 forbidden cloudflare-nginx

I’ve setup a tunnel from docker using cloudflared and have connected a few containers using that tunnel with different domain names. I have a problem with this specific domain name when trying to use it as a public hostname I keep getting 403 forbidden cloudflare-nginx, if i change the hostname to one of the other domain it works, I tried comparing all the settings with another domain that’s working.
I don’t know what I’m missing. I would appreciate any help.

Could you share your nginx reverse proxy configuration? Maybe there is an SSL misconfiguration that is causing the issue. You could test this by disabling Cloudflare’s Proxy for that domain name and see if you can access the site.
