Monitoring a Dockerised Celery Cluster with Flower

hello, I have installed celery on Django project, and I have added the required configuration.. I wanna use it for sending emails, so I installed redis on linux server, no error appear when I turn on the worker and Django server.. the Task is received.. but the email never delivered.. why ?

Hey, the screenshots in the article are missing, hence leading to confusion as to what is demonstrated through various configs.
