yii\redis\SocketException: Failed to read from socket.
I am encountering this issue intermittently on random requests. Based on my observations, it occurs when the connection remains idle for 5 minutes. Our DigitalOcean Redis service has a timeout set to 300 seconds (5 minutes), causing the connection to be closed from the server side. However, Yii Redis does not properly reopen the connection when this happens.
My Yii Redis configuration has retries set to 2, but the issue persists.
I have reviewed the yii\redis\Connection class, which already includes an implementation to handle such scenarios, as referenced in this issue: Exception 'yii\db\Exception' with message 'Failed to read from socket. #91. However, it seems that the fix does not work in all cases.
Could you please look into this? Please let me know if you need any more details.
