Using LetsEncrypt with PufferPanel

LetsEncrypt provides free SSL certificates and are great way to enhance the security of your PufferPanel installation

For the purposes of this guide, replace “” with your PufferPanel installation’s domain name.


Enabling SSL on the panel will require that you update your pufferd configs to point to the updated URL. Refer to the directions below to do this.

Modify nginx config file

Find your pufferpanel.conf configuration file located in either /etc/nginx/sites-available or /etc/nginx/conf.d

Add the following location block to your nginx config file

location /.well-known/acme-challenge/ {
    try_files $uri =404;

Here is some context for where you should place it

    location / {
        try_files /public/router.php =404;
        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
        fastcgi_pass unix:/var/run/php7.2-fpm.sock;
        fastcgi_index router.php;
        fastcgi_param SCRIPT_FILENAME \$document_root\$fastcgi_script_name;
        include /etc/nginx/fastcgi_params;

    location /.well-known/acme-challenge/ {
        try_files $uri =404;

    location /assets {
        try_files /app/\$uri =404;

Make sure to reload nginx

systemctl restart nginx

Grab the LetsEncrypt client

sudo -i #(or su root)
apt install -y certbot

Now generate the certificates

certbot certonly --webroot -w /srv/pufferpanel/ -d #news
certbot renew --webroot -w /srv/pufferpanel/ -d #Renew
Go back to your pufferpanel.conf and update the server block with the directives below (make sure to replace with your domain)
If a directive already exists in your server block, replace it with the one below
listen 443;
ssl_certificate /etc/letsencrypt/live/;
ssl_certificate_key /etc/letsencrypt/live/;

Updating pufferd configs

Once your panel is using HTTPS, you will need to update your pufferd configs to use the new URL.

Update the following file, changing http to https where appropriate:
Restart the pufferd service
sudo service pufferd restart

Enabling HTTPS on pufferd

Copy the full chain certificate and the private key files from LetsEncrypt into pufferd.

cp /etc/letsencrypt/live/ /etc/pufferd/https.pem
cp /etc/letsencrypt/live/ /etc/pufferd/https.key

Change the owner and group of the files

chown pufferd:pufferd /etc/pufferd/https.pem
chown pufferd:pufferd /etc/pufferd/https.key

Restart the pufferd service

sudo service pufferd restart

Next, update the node through the panel to have the private IP set to be your domain.
