Hi there,

A 504 error indicates your n8n instance can’t reach the license server. Since you’re on AWS ECS Fargate, check the following:

Network connectivity:

  • Verify your ECS tasks have outbound internet access (requires NAT Gateway if in a private subnet)

  • Check security groups allow outbound HTTPS (port 443)

  • n8n uses Cloudflare to host the license server and you need to allowlist the full range of Cloudflare IP addresses n8n Docs - see Cloudflare IPs

Can you check your ECS task’s network configuration and security groups, and share any additional error details from your container logs?
