Can't get load balancer in a healthy state

Howdy! I’m trying out the k8s beta and it’s been great so far. I have two clusters, both with load balancers sitting in front. One of the load balancers is working great and has had no issue. The second hasn’t been in a healthy state since I created it. The droplets are hosting a third party app that doesn’t respond to /, but it does have another healthcheck URL.

The solution it seems was to put nginx in front of the app, which I’ve done and it responds with a 200 on /, but the load balancer still thinks the droplet is unhealthy. I’ve tried various configurations for TCP and HTTP checks on various ports.

Using kubectl proxy, I’ve been able to get a 200 response from the / endpoint, so I’m not really sure what else I need to do. Any help would be great. For reference, here’s my nginx and k8s service config: https://gist.github.com/mike-engel/a1c11cd6d0edcdab6fd912619b33d972

Thanks!
