Please follow the How to report a problem instruction by providing all necessary information, like platform, interpreter, extension and librabbitmq versions. Also, check Things to check before reporting a problem list (especially no. 4 - You has correct RabbitMQ credentials.), maybe you met one of typical errors that happened before.

I got the same issue, and my issue was related to using read_timeout wrongly to begin with. Setting it to 0 fixed the issue, i am assuming this is the case for you as well.
