Hi. In following the directions on installing an air-gapped rancher environment I'm at the point of setting up an nginx load balancer for the front end, and the sample config file does not work at all: https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/infrastructure-setup/nginx-load-balancer I get two errors:

1 - the first proxy_pass in the http stanza complains that it's not allowed here.
2 - I get this error: host not found in upstream "rancher_servers_https" in /etc/nginx/nginx.conf

The Rancher 2.5 documentation doesn't have that http section in it at all. I'm running this on RedHat8 any ideas?
