Celery connection to Redis throwing "timed out" error only when delay method called from Django view

Question

I am perplexed with this error and looking for some expert help. Here are the details -

• I am running a Django application with celery to schedule and execute tasks
• I use Azure Cache for Redis as the celery backend and broker
• Azure Redis has SSL port enabled and non-SSL port disabled
• I have configured SSL using URL scheme (rediss://) as well as celery config (broker_use_ssl and redis_backend_use_ssl)
• My Task is defined in one django app and the view is in another (though they are deployed together)
• Everything works also fine in my local setup, where I don't use SSL on redis
• My django server is running with gunicorn inside a docker container

Everything works just fine when celery-beat schedules a task and workers pick them up to execute. They both are able to communicate with Redis fine.

However, when I call a task from my django view directly, with delay function, I see a timeout error on connecting Redis.

Here is how I am calling the task (removed some boilerplate code for brevity):

from mydjangoapp import tasks

def MyViewFunction(request):
    tasks.MyTask.delay(param1, param2, param3)

Here is the error I see :

kombu.exceptions.OperationalError: Error while reading from <my-redis-server-url>:6380: ('timed out',)

Can someone please point out what happens differently when I call task.delay() from django view than celery workers?

Not sure if I missed any important detail. Please let me know and will update it in the Question. Thanks.
