Status changes to Not Connected after few hours

Hello there,

The Redis plugin shows that the connection to the server is disconnected every few hours after restarting. Once Redis is restarted from the server side, the status is changed to Connected again. I had to restart Redis whenever I saw the Status as Not connected.

I have installed Redis on Plesk using Docker. This is the diagnostic from the plugin:
