Hi.

We have configured HUE Load Balancer with cloudera manager.
And we also have an additional iptables NAT rule that forward 443 -> HUE Load Balancer port for a user friendly experience.

We run HUE LB on port tcp/7180.

iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 7180

End users access HUE with a CNAME in the browser, let’s stay https://internal-hue.company.net.
The actual HUE instance is on AWS and we have a VPN from our internal network so the server is using the standard VPC hostname ip-X-X-X-X.<aws region>.compute.internal.

We now get the following warning banner from HUE saying that we are accessing non-optimized hue, even if we are going through the HUE LB.

"You are accessing a non-optimized Hue, please switch to one of the available addresses: https://ip-X-X-X-X.<region>..compute.internal:7180"

Has anyone seen this problem before when using CNAMES instead of hostname with HUE LB?
