To work around this issue, perform the following checks:

• Please verify the root password is not expired for this NSX Manager node.
  1. Ensure you can SSH to any of the NSX Managers using 'root' account. 
  2. If the root SSH is disabled, try to SSH as 'admin', and then run the command "st en" to test the root login.
  3. If the 'root' password is expired, it will show warnings to change the password.
     
     
• Check the Windows local file security settings by verifying the below file properties:

1. 1. Right-click the target file.
   2. Select Properties.
   3. In the General tab, click "Unblock" next to "This file came from another computer and might be blocked to help protect this computer."
