How to update Generic OIDC redirect_uri from http to https

Hello. I’m relatively new to AWX and am attempting to configure Generic OIDC. I’ve worked with my auth team to get the OIDC Key, Secret, and Provider URL configured. When I try to login to, I get an error: Invalid redirect_uri. I can manually update the uri in the request which then completes and provides the login page.

The call is https://auth.sso.MYDOMAIN.com/fss/as/authorization.oauth2?client_id=MYCLIENTID&redirect_uri=http://MYSERVER/sso/complete/oidc/&state=SNIP&response_type=code&nonce=SNIP&scope=openid+profile+email. If I change the redirect_uri from http to https, then it works fine.

I have set the “Base URL of the service” in the Miscellaneous System Settings to https://MYSERVER, but this doesn’t seem to be picked up and used in the OIDC call.

This is running in a test environment with minikube and an nginx server running on the VM configured with proxy_pass to an upstream backend that provides the SSL offloading.

$ cat kustomization.yaml

# Specify a custom namespace in which to install AWX

$ cat awx-finit.yaml

Any help on how to update/fix the redirect_uri to use https would be greatly appreciated.
Thanks,
