Hello,

Indeed, what I could suggest is setting up Nginx as a reverse proxy that way you could use Let’s Encrypt to secure your installation.

Your Nginx reverse proxy server block would look something like this:

server {
        listen 80;
        listen [::]:80;

        server_name your_domain.com;

        location / {
             proxy_pass http://localhost:8080/;
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_set_header X-Forwarded-Proto $scheme;
             proxy_set_header X-Forwarded-Port $server_port;
        }
}

Then you could follow the steps here on how to setup Let’s Encrypt:

Hope that this helps.
