I can't deploy n8n with Redis and Postgres. After I tried changing variables and fixing access for Postgres, everything broke. Please provide the correct environment variables, or help me configure everything to get it working again n8n.

This appears to be an issue with the way your n8n is connecting to your database

Please go into the variables and change the:

  • QUEUE_BULL_REDIS_HOST from ${{Redis.REDISHOST}} to ${{Redis.REDISHOST_PRIVATE}}

  • QUEUE_BULL_REDIS_PORT from ${{Redis.REDISPORT}} to ${{Redis.REDISPORT_PRIVATE}}

For both the Worker and Primary
