Openstack Trove - Polling request timed out

Question

We are trying to deploy OpenStack environment for our application and while deploying trove service we are facing the below error:

  File "/usr/lib/python3/dist-packages/trove/common/utils.py", line 207, in wait_for_task
    return polling_task.wait()
  File "/usr/lib/python3/dist-packages/eventlet/event.py", line 125, in wait
    result = hub.switch()
  File "/usr/lib/python3/dist-packages/eventlet/hubs/hub.py", line 313, in switch
    return self.greenlet.switch()
  File "/usr/lib/python3/dist-packages/oslo_service/loopingcall.py", line 154, in _run_loop
    idle = idle_for_func(result, self._elapsed(watch))
  File "/usr/lib/python3/dist-packages/oslo_service/loopingcall.py", line 349, in _idle_for
    raise LoopingCallTimeOut(
oslo_service.loopingcall.LoopingCallTimeOut:
    Looping call timed out after 870.99 seconds

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
