WSS instead of WS

Hi Mate !
Do you know if there's a way to create a WSS server instead of WS ?
If yes, do I need a key and creditential ?
Thanks for your answer !

Hi @neilyc,

The easiest way to use WSS/HTTPS is by using NGINX as a proxy:

You can get free TLS certificates from LetsEncrypt (, they're awesome and really easy to configure for NGINX, their CLI tool will configure mostly automatically for your environment.
