I'd say that anything worth using has been taken away leaving only the evils to fester, but Twitter dying is probably a net positive for the world lol.

Hi all! This is my first real post on the fediverse, coming to you live from my own Lemmy instance, which took me way too long to set up. Turns out, the provided docker-compose.yml file provided by the official Lemmy documentation does not allow outbound access to the internet, which prevents users from seeing other instances on yours. For SEO's sake, I was receiving the following error message: error trying to connect: dns error: failed to lookup address information: Try again

Anywho, I updated the docker-compose.yml file to put all containers on one network, and allow that network outbound access while restricting inbound access to only ports 80 and 443, which worked a treat.

version: "3.3"

networks:
  lemmy:
    internal: false

  proxy:
    image: nginx:1-alpine
