"I'm currently utilizing Strapi as my headless CMS, but recently encountered a problem where the frontend requests were returning a 404 error. Concerned, I logged into my Strapi dashboard only to discover that all of my data had vanished.

Upon further investigation, I attempted to access my data directly from the Railway project, only to be prompted with the message stating that I need to ensure the following variables are configured:

PGHOST

PGPORT

PGUSER

PGPASSWORD

PGDATABASE

DATABASE_URL

Strangely, I haven't made any changes to these variables. I'm at a loss for what to do to retrieve my data. Any guidance or suggestions would be greatly appreciated."
