@Nusnus I will work on reproducing the issue, I could not reproduce in a simple docker environment so far.

Check out https://pytest-celery.readthedocs.io, it might be useful.
It seems that Control commands from workers with kombu <5.4.0rc cannot send control commands to workers with kombu >=5.4.0rc. For example ping is never received if using kombu 5.4.2 if sent from a worker in 5.3.7. We are using redis backend with sentinels.
I tried also to install celery 5.5.0b2 and force kombu 5.3.7 as a test. And the worker appears in my flower ui, which is running on older kombu.
However the moment I update it to 5.4.0, it dissapears and never receives any commands from flower. (using celery debug log level I can see that nothing gets received by the worker)
Side note, updating the flower env to newer kombu now sees the worker, but does not see other workers running on <5.4.0rc. Tasks are still picked up by workers.
