All Stackdriver logs for the load balancer have the following for each request as the status details: failed_to_connect_to_backend We've tried the following with no luck: - Restarted GCE instances in backend service - Recreated the backend service - Recreated the HTTPS load balancer - Switched the balancing mode of the backend service to rate instead of utilization since monitoring was stating the backend service CPU utilization was 500% (another red flag) We are, however, able to directly connect to the GCE instances within the backend service via external IP. Have not heard much back from Google support.
