Hi @ElBaud, welcome!
This appears to be a bug in the Coolify n8n template, The Task Runner is incorrectly trying to connect to the main instance instead of the worker:
The Fix: You just need to update the N8N_RUNNERS_TASK_BROKER_URI environment variable in your compose file to point to the n8n-worker container:
N8N_RUNNERS_TASK_BROKER_URI=${N8N_RUNNERS_TASK_BROKER_URI:-http://n8n-worker:5679}
Also, make sure the value is correctly configured in Coolify environment variables:
