Hi! It's difficult to say what might be wrong without seeing the logs or knowing more about your environment and installation method. You can try retrieving the logs by running docker logs planka-postgres-1.

PostgreSQL Database directory appears to contain a database; Skipping initialization

2025-06-06 14:24:41.494 UTC [1] FATAL: database files are incompatible with server
2025-06-06 14:24:41.494 UTC [1] DETAIL: The data directory was initialized by PostgreSQL version 14, which is not compatible with this version 16.9.

Ah, that makes sense. Your PostgreSQL version has changed, and the previous data isn't compatible with the new version. You'll need to back up the existing data and restore it into the new version.
