Information on your n8n setup

  • n8n version: (where do I see that)

  • Database (default: SQLite): Postgres

  • n8n EXECUTIONS_PROCESS setting (default: own, main):

  • Running n8n via (Docker, npm, n8n cloud, desktop app): I’m running it on docker compose so here is the compose file.

  • version: ‘3.8’

hello @Eldersson

I can’t check the docker compose config, as it was passed here in one line.

As I can see, you have some issues wuth the config.

the ports binding is incorrect (localhost should be specified only if you are on the same host).

N8N_BASIC_AUTH variables may be removed, n8n doesn’t support them since v.1

N8N_PROTOCOL is https, but you didn’t provide any SSL certificates.
