What is the issue you’re encountering

After setting up the certificates proerply via certbot for my nginx reverse proxy, im unable to connect to my domain via https, i don’t even get logs for https connections for that domain.

What steps have you taken to resolve the issue?

first i’ve suspected the certificate itself, so i made sure that i have it installed on the nginx image properly on docker, with the proper permissions for those files and properly set up nginx to use them. Then i’ve made sure that the 443 port is exposed (via nc -zv apii.test.okiynai.com 443 command, it outputed Connection to apii.test.okiynai.com (104.21.90.191) 443 port [tcp/https] succeeded! ) , and it should just work now.

What is the current SSL/TLS setting?

Full

What are the steps to reproduce the issue?

so i have a machine ( with dynamic ip address ) and i’ve setup cloudflared on it. Now it works

Do you have advanced certificate manager? Cloudflare does not provide free certificates for 2nd level subdomains like api.test,
