I have done the following while debugging the failing backend container:

• Audited the secrets and environment variables
• The database OpenShift service object is referenced as an environment variable in the backend container
• Checked network policies exist and are allowing same namespace traffic
• The database container is deploy successfully and accepting traffic
• I can log into the database using the dev database secrets
• Refactored the django database configuration to simply debugging

Initial problem ended up being the network policy. Although it was setup and present you can add the specific license plate number to the network policy to be more specific. This was not required in other nr-* repos referenced during pipeline work.
