Cause
They are several reasons this issue can occur, that can be seen below.
1. Invalid username.
2. Invalid domain name (if the account is local to Nutanix cluster then a domain value is not needed)
3. Invalid Password
4. A role was not mapped to the prism user.
5. Verify the account exist in Prism Element. If you are using Prism Central, you must go to the cluster and access the Prism Element UI to add a user.
Solution
Verify the user, domain, and password used.
A user maybe able to access the Prism WebUI, but may not have access to RestAPIs.
Check the prism_gateway.log from the Nutanix side for the real error:
