Retry did not work after (104, 'Connection reset by peer')

[aakashb09]

I am using a reminders system using Redis, Celery Beat, RabbitMQ, Worker

Using Redbeat, I save a reminder in Redis, then Beat picks the reminder, puts it into a queue from where the worker picks it up, and sends the reminder.

My Redis instance is hosted by Upstash and since there are idle times >5 mins, Upstash resets my connection.

To mitigate this, I added a retry_period: -1 argument.

My questions are:

1. Celery is configured to read from Redis every 5 minutes, this is defined in the DEFAULT_MAX_INTERVAL=300 right?
2. I am assuming if I didn't see this
   logger.warning('beat: Retrying Redis connection in %s seconds...', retry_state.next_action.sleep)
   line anywhere in my logs, the retry has not happened, right?
3. To not keep the connection idle, I have added a periodic task that repeats every 4 mins. However this doesn't solve the retry not happening, how best to go about this?

celery==5.2.7
celery-redbeat==2.0.0
