Question

Loadbalancer reports droplet with express server and Nginx Reverse Proxy as down

Hi there,

The setup for my network is as follows:

  • A DO load balancer with SSL termination, as explained here
  • A DO droplet with an Nginx reverse proxy, using the config generated by the DO NGINXConfig tool, found here

Just to note also, I have enabled Proxy Protocol on my load balancer and passed the required headers where necessary.

For some reason though, my load balancer is saying my droplet is down when its not.

I assume I’m missing something but was wondering if anyone has any idea as to what.

Thanks!

Hi there,

What I could suggest is changing the health check from HTTP to TCP.

DigitalOcean Loadbalancer TCP config

Also, make sure that the check port matches the one that your backend service is running on.

Let me know how it goes! Regards, Bobby
