SSL Error with st2 sensor connection redis

Getting these errors while connecting to redis with SSL. A normal action runs fine, sensor seems to be having problem. I did try to use the fixes mentioned in https://github.com/eventlet/eventlet/issues/371 but none of the different combinations of library versions seem to work for my case.

lib versions tried:
redis==latest/3.3.5
eventlet==latest/0.17.4
Flask-SocketIO==4.2.1
dnspython==latest/1.16.0

Start with st2reactor/container/sensor_wrapper.py and the sensor entry point shown at /opt/stackstorm/packs/st2sensors/sensors/vmc_event_notification_sensor.py:56, then trace the Redis subscription through redis/client.py and redis/connection.py. Reproduce the SSL connection timeout and determine whether the sensor path differs from the working normal action. Done means the sensor can subscribe over SSL without the reported timeout, with the relevant behavior covered by a regression test.
