I’ve followed the instructions to install Rocket.Chat on a droplet of DigitalOcean: https://marketplace.digitalocean.com/apps/rocket-chat
It worked fine while I was trying to connect directly via the IP.
Then I’ve set up a subdomain and generated an SSL certificate with the command:
rocketchatctl configure --lets-encrypt --root-url=https://chat.yourcompany.com --email@example.com
But now it doesn’t work anymore, and the page only displays “Bad Gateway”.
I think I’ve done things correctly with the subdomain: an A record and NTS records sending to DigitalOcean.
I have no idea what could be wrong, I’m new to Rocket.Chat and DigitalOcean.
Any help is welcome, thanks!
