    Are you deploying to Consumption SKU? Since the Inner Exception that’s causing the NodeJS worker to shutdown is TLS Timeout, I’m wondering if you may be encountering a similar threading-related problem described in the following post:

    On a side note though, could you expand on your use case with the Time Trigger? Do you necessarily need to create Redis connections at time intervals? Azure Functions does have an event-based Redis Trigger which might work better: Overview of Azure functions for Azure Cache for Redis (preview)
