Why adding a host in RHV-M is failing/taking more time to complete

Issue

• Adding a host to RHV-M fails for the 1st time. However adding it again after the 1st failure is working without any issue.
• Adding host to the manager is taking more time than expected.
• Below logs are shown in the setup logs.
