I have successfully created a separate user openstack and set the user as administrator and set permissions for vhost /. I have verified authentication and it was susccessful. But when nova-conductor is sending a connection request it was refused under mechanism AMQPLAIN --invalid credentials. I have googled and attempted various workarounds but couldn't fix it. Can anyone please help to resolve this issue.

Please help to resolve the issue. User was successfully authenticated but still error shows invalid credentials for AMQPLAIN login
Screenshot
transport_url = rabbit://openstack:password@192.168.1.104 nova conductor was initially connected to amqp server but when i launch a vm, nova-conductor connection is reset by peer and login is refused later under authentication mechanism amqplain. All other openstack services are connected and working fine. Verified through web page of rabbitmq. Can you please advice a workaround.
I am able to send curl from both controller node and compute node. curl -u openstack:password 192.168.1.104/api/vhosts and it was successful. I was able to login using browser and verify the details and openstack user is having the permissions set. But when i spawn an instance nova-conductor log shows login refused under mechanism AMQPLAIN --invalid credentials. Any advice please on resolving the issue.
openstack user created during deployment. Yes other services eem to work fine. Even for conductor connection was established and working normally. If i try to launch a VM instance, the error pops up that the credentials are invalid. nova conf file settings are same in both controller and compute node. I have restarted all nova services and rabbitmq multiple times. debug is also enabled. i am using openstack queens version. package versions are the same.
