I'm running Evolution API on Railway and facing a session persistence issue.

The QR Code is generated correctly, the WhatsApp device connects successfully, and the instance shows as connected in the Evolution panel.
However, after some time (or after a Railway service restart), the WhatsApp session disconnects automatically, requiring a new QR Code scan.

This happens even though Redis and PostgreSQL are configured.

What did you expect?
