I’m running n8n with docker behind an nginx proxy. I’m able to load the frontend but all urls with /rest return status code 404

hello @Renaut

I see some issues with the docker config:

- N8N_PROTOCOL=https   # should be http
- N8N_PATH=${N8N_PATH:-}  # that one maybe breaks your instance. Usually you don't need to set it

- /var/run/docker.sock:/var/run/docker.sock # usually you don't need to mount that one
