I am getting this error:
Error frontend: 502 Bad gateway 99.110.244:443 2017/09/28 13:03:51 [error] 34080#34080: *1062 peer closed

Here is what worked for me. I had a server section with server_name setup with a wildcard search and had to do the following in the location section:
proxy_ssl_name $host; proxy_ssl_server_name on; proxy_pass https://istio-ingress-gateway
