502 on new install

Using docker via unraid, followed all the instructions that in the overview section. When I start it up, I get 502 bad gateway when trying to access it, and after ~5 minutes of uptime the logs start getting spammed with “waiting for mysql server to be ready: %s (1045, “Access denied for user ‘root’@‘172.18.0.1’ (using password: YES)”)”

Not sure why it’s trying to connect to 172.18.0.1, DB_HOST is set to 192.168.4.33.

Still having this issue
