Protect The Lounge with HTTPS

In this guide, we will see how to easily configure The Lounge to be served over HTTPS for better security and privacy.

First, you need an HTTPS certificate. Let’s Encrypt is a free, automated, and open Certificate Authority that provides completely free HTTPS certificates.

Assuming you have a valid email address at, and want to serve The Lounge at, run these commands on your server:

git clone
cd letsencrypt/
./letsencrypt-auto certonly --standalone --email -d

Follow the instructions on screen. This should generate a private key, as well as your HTTPS certificate that will expire after 90 days.

Open your configuration file, located at ${THELOUNGE_HOME}/config.js and look for the https key, and set the following values:

  • Change enable to true
  • Set key to the private key path that was generated, privkey.pem
  • Set certificate to the certificate path, fullchain.pem

Let’s Encrypt will create its /etc/letsencrypt folder as root user, so you might have to change the owner of these files to the user that runs The Lounge.
