Сonsumer: Cannot connect to amqp://guest:**@127.0.0.1:5672//: [WinError 10061] Connection not established... Who can help?

Question

Python

Followed instructions for connecting celery here. At first everything worked, tasks got into the queue, but were not executed. Reinstalled celery (more modern version) - everything stopped working. I tried to reinstall the broker and different versions of celery, the result is the same. Searched for a lot of information in search engines - nothing helped. Who can tell? I'll give you some code.

Successfully installed amqp-5.0.5 billiard-3.6.3.0 celery-5.0.5 kombu-5.0.2 vine-5.0.0
