[Bug]: Redis connection doesn't repair itself, health check says ok when it's not

[wipash]

What happened?

The connection between LibreChat and Redis was interrupted, and it doesn't reestablish itself.

When signing in, the login page loads fine, but the login request to /oauth/openid fails with 500 - An unknown error occurred.

Console logs below

The LibreChat health check says it's okay, so Kubernetes doesn't restart the pod:

❯❯ curl https://chat-dev.hlms.cloud/health
OK

Restarting LibreChat fixes the problem.

Version Information

librechat-dev:12f45c76eea83022e7be674b15a8e764a5bf0f94

Steps to Reproduce

1. Configure LibreChat with Redis
2. Restart Redis while LibreChat is running
3. Problem appears

What browsers are you seeing the problem on?
