502 Bad Gateway with GKE nginx

Question

Im trying to forward to my api on /api/ and my UI on /

My UI is all working fine and my logs for the nginx ingress and api (which ive tested with port forwarding) are all working fine. But when i curl or go to IP/api/healthz (which would be the healthcheck for Hasura) I get 502 bad gateway
