Error with certbot authentification

My domain is and I am trying to run Pterodactyl Panel using SSL with Nginx Proxy Manager and Cloudfare. I am running Pterodactyl Panel and Nginx Proxy Manager in dockers (with docker-compose) on Ubuntu 22.04.1 LTS on Oracle Cloud. I generated a SSL Origin Server certificate on Cloudflare and I put the certificate and the key here /etc/letsencrypt/live/ /etc/letsencrypt/live/ Cloudflare is configured to like this for DNS:

Nginx Proxy manager is configured like this:

Pterodactyl conf is this: `server_tokens off;

server {
listen 80;
return 301 https://$server_name$request_uri;

server {
listen 443 ssl http2;

root /var/www/pterodactyl/public;
index index.php;

access_log /var/log/nginx/;
error_log  /var/log/nginx/ error;

# allow larger file uploads and longer script runtimes
client_max_body_size 100m;
client_body_timeout 120s;

sendfile off;

location ~ /\.ht {
    deny all;


When is start the docker with the panel I receive these errors:
Pterodactyl runs on 82 and 442 ports, because on 80 and 443 runs the Nginx Proxy Manager.
What is the problem with this situation?

Copying the Cloudflare Origin CA certs to that location will cause Certbot to fail. Certbot places symlinks to its own cert files in that folder and will fail when it see other files there.

That isn't the reason for the 404 "invalid response" error in your standalone request though.

If you have valid Cloudflare Origin CA cert why do you even need one from Let's Encrypt?


How can I put the Cloudflare Origin CA cert on the Pterodactyl Panel? I don't want another cert from Let's Encrypt, but this is how Pterodactyl Panel works with SSL.

That's a great question for Pterodactyl support or your hosting service :slight_smile:


If you have a working Proxy...
Why don't you use it?
[and put Pterodactyl behind it]


First I did this, but then I had a problem with a plugin for Pterodactyl and I want to try this, but is more simple to put it behind the proxy. Thanks,
