Connection Lost + Cannot Get /

Bug Description

After upgrading n8n, the n8n_editor container no longer works. The interface loads for a few seconds and then displays “Lost connection”. It seems to be receiving a SIGTERM and shuts down, with no changes made to the stack.

This only started after the update — no environment or stack changes were made.

What I see in the logs:
• Received SIGTERM. Shutting down...
• Driver not Connected

What I’ve tested:
• Redis responds with PONG
• PostgreSQL is running and accessible
• Network (docker network inspect) shows all services correctly connected
• Tried with both latest and specific version 1.92.2, same result

Infrastructure
• Ubuntu Server 22.04
• Docker Swarm
• Redis: running fine
• PostgreSQL: running fine
• n8n running in queue mode with three services (start, webhook, worker) using Traefik reverse proxy

Expected Behavior

Editor should stay online and not crash or show lost connection, as it did before the update.

n8n Version
1.92.2 and latest (both tested)

Database
PostgreSQL

Execution Mode
queue

To Reproduce

1. Deploy n8n in queue mode with editor, webhook and worker services (Docker Swarm)
2. Open the editor URL in the browser
3. Wait a few seconds
4. Editor disconnects and shows “Lost connection” message

Expected behavior

Hey @dandomribeiro,

We have created an internal ticket to look into this which we will be tracking as "GHC-2267"

I also experienced this, loop saying "connection lost" (then connects again) every 1-2 seconds, within any workflow
reverted to 1.94
