openstack HA: sometimes getting unable to establish connection error

In My 2 controller openstack HA setup ( using 2 mysql galera clusters) sometimes I am getting the below errors when I try to create heat stack which is used to create a instance with floating IP.

1) ConnectionRefused: Unable to establish connection to http://controller-vip:9696/v2.0/ports.json?tenant_id=ca1d10786fdc41698e276a8f22d98741&device_id=183bea96-b0da-42a5-a731-713882598624

I verified neutron port 9696 on both controller node they are in listening state.

2) keystoneauth1.exceptions.connection.ConnectFailure: Unable to establish connection to http://controller-vip:8004/v1/ca1d10786fdc41698e276a8f22d98741/stacks

I verified heat port 8004 on both controller node they are in listening state.

Every time I am not getting these errors. Only sometimes I am getting this error. When I looked at syslog I have observed below warnings. Not sure whether these are related to above error.

Warning] Aborted connection 102541 to db: 'keystone' user: 'keystone' host: 'controller01' (Unknown error)
[Warning] Aborted connection 103782 to db: 'nova' user: 'nova' host: 'controller01' (Unknown error)

Could you please help me in fixing this issue.

Thanks, Satya.P
