Describe the problem/error/question
I’m running n8n in Google Cloud VM using docker-compose and traefik, but I’m not being able to properly work with task runners enabled, every time I get "WARN Found runner unresponsive" and:
error | Task runner connection attempt failed with status code 403 {"file":"task-broker-server.js","function":"response.writeHead"}
And the same error keeps spamming in the logs, and I’m not able to execute any code node.
This only happens when I set N8N_RUNNERS_ENABLED=true
I’ve tried following what others have said in posts like this Self-hosted N8N - Task runner connection attempt failed with status code 403 but haven’t been able to fix it.
What is the error message (if any)?
error | Task runner connection attempt failed with status code 403 {"file":"task-broker-server.js","function":"response.writeHead"}
