Additional context, if any

I am using local-path to provision the volumes
I am using a secret to pass the initial username and password.
I am using an already provisioned PostgreSQL instance using the bitnami chart - 15.5.31
I am using external postgres operator to create the database the user credentials and the secret I pass as an existing secret.
All secrets values are passed correctly to the pod. The database is being seeded after nextcloud is deployed. There are no error logs in the pod. When I git the domain I get the above error.

Any advice would be appreciated.

Start with the supplied values.yaml and the Helm chart's persistence, config, and externalDatabase settings for chart version 5.5.6. Check the Nextcloud pod behavior and confirm when the external PostgreSQL database is seeded relative to deployment. Done means a clean installation completes without the CAN_INSTALL error.
