Only allow traffic to Droplets through Load Balancer

Load Balancing Firewall DigitalOcean

I have two droplets, a firewall and a load balancer.

I can access HTTP on droplets & load balancer address.

If I change the Firewall Inbound rule from
HTTP TCP 80 All IPv4 All IPv6
HTTP TCP 80 {IP of Load balancer]

The Load balancer health checks then report both Droplets down. Health checks are performed on

I get HTTP response:
503 Service Unavailable
No server is available to handle this request.

Found the answer: add the name of the load balancer to the firewall rule rather than it’s public IP address
