"Name does not resolve" error doesn't say which name failed to resolve

[DMRobertson]

Would be nice-to-have if this error message said what it was trying to resolve:

$ docker run -v $(pwd)/tests-e2e/mas-config.yaml:/config.yaml ghcr.io/matrix-org/matrix-authentication-service:main config sync
2023-08-21T10:48:24.218439Z ERROR cli.config.sync{prune=false dry_run=false}:db.connect: mas_cli::util: error=could not connect to the database

Caused by:
    0: error communicating with database: failed to lookup address information: Name does not resolve
    1: failed to lookup address information: Name does not resolve
