I’m creating a clean installation of ERPNext v12 on Docker in order to restore a backup, with the ultimate aim of upgrading to v13.
The configuration is pretty straightforward and when I spin up docker-compose I don’t see any obvious errors, MariaDB comes up as do the workers and Traefik complete with the certificate.
However, when I attempt to connect to the site through a browser I get a 502 Bad Gateway error and Traefik logs the following error…
traefik_1 | time="2022-03-15T10:27:29Z" level=debug msg="'502 Bad Gateway' caused by: dial tcp 172.19.0.2:80: connect: connection refused"
which would imply that the backend behind Traefik, presumably ERPNext, isn’t running and accepting connections.
I would be grateful for any thoughts on how I can trace and resolve this error.
