Workaround

source /opt/netbox/venv/bin/activate
pip install "redis<8"

Thank you for the detailed report! This appears to be a duplicate of #22369, which was opened a short time earlier and describes the same redis-py 8.0 incompatibility with Unix socket connections (the same ValueError: Cannot enable maintenance notifications for connection object that doesn't have a host attribute traceback).

Could you confirm this is the same issue you are seeing? If so, it would help the maintainers to consolidate discussion over there.
