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. |

This ended up being due to SNI getting enabled on our HTTPS binding in IIS when using a Let's Encrypt cert. Apparently, the GCP HTTPS LB does not like SNI.
