@Taragolis traced the issue to docker/docker-py#3256 which is caused by psf/requests#6707 for the moment lets pin request version till they release a fix

[Taragolis]

Maybe better add requests>=2.27.0,<2.32.0 as dependency for Docker Provider and pin it here, and keep other providers unchanged?

As far as I understand changes in 2.32.x affect only docker-py lib, if someone do not need to use Docker Provider, then they could use requests up to request 3 (which not released yet)
