Issues reaching app externally via Ambassador

Describe the bug We are unable to reach our app externally to our network. Also, we are rerouted to an incorrect URL.

To Reproduce Steps to reproduce the behavior:

Go to preprod.[app].com
See error
Sometimes we are routed to [subdomain]-preprod.[app].com This is a related URL but unintended behavior.

Expected behavior We expect to be routed to our app successfully via Ambassador.
