It would be helpful if you posted the API and/or conductor logs if there are any error messages or stack traces in them. Please feel free to drop by the #openstack-containers IRC channel on freenode to get help! My IRC handle is Drago.

Having only the error to go on, here's what I can say:

This is the patch that changed the OS::Neutron::HealthMonitor resource to Magnum::Optional::Neutron::Pool::HealthMonitor: https://review.openstack.org/#/c/338535/. It includes Heat environment files [1] to map Magnum::Optional::Neutron::Pool::HealthMonitor to either OS::Neutron::HealthMonitor or OS::Heat::None (effectively enabling/disabling it). The environment files were moved in https://review.openstack.org/#/c/346151/.

The only reasons I can think of for this occurring are:

Your magnum service code is not up-to-date. When you update the code, make sure the magnum API and conductor get restarted, or else the new versions of python files will not be picked up. The currently-running Magnum processes may still be looking in the location the environment files were before they were moved and not be able to apply the environment files to do the resource remapping.
with_master_lb.yaml and/or no_master_lb.yaml are completely missing from magnum/drivers/common/templates/environments.

ENV Files are on the right place

root@magnum1:/opt/magnum-master/magnum/drivers/common/templates/environments# ll
  no_master_lb.yaml
  with_master_lb.yaml

If have checked the code by moving the environments files - i see that if i moved the files the errors changed to something like "Can not access files", so python schould used the right code
