Resolution

1. Make sure there is no proxy configured on vCenter server and cloud gateway. 

2. vCenter server SSO password for vc.example.com should not have any of the following special character. 

These special characters are not supported in SSO passwords:

• Non-ASCII characters
• Ampersand (&)
• Semicolon ( ; )
• Double quotation mark ( " )
• Single quotation mark ( ' )
• Circumflex ( ^ )
• Backslash ( \ )
• Percentage (%)
• Angle brackets ( < , > )

3. Root password is not expired on the vCenter server. 

4. If none of the above is the scenario, then reboot the vCenter server reboot and rerun the script on the vCenter server.
