I followed the steps in the quick-start guide, but kept running into the following error
2026/04/26 18:14:06 ERROR: connecting to database: dial tcp: lookup postgres on 8.8.8.8:53: dial udp 8.8.8.8:53: connect: network is unreachable
I was able to overcome this by defining adding the following to my .env file (missing from the .env.example):
DB_HOST=postgres
The host machine has a fresh install of Debian 13 (no DE).
