Environment

• VMware SDDC Manager 4.5.x
• VMware SDDC Manager 5.x

Cause

• The hostname field contains spaces in the FQDN of the host after the inverted quotes( " ).
• The precheck determines the spaces as invalid characters and hence fails with the error. 

Resolution

• Remove all the spaces in the hostname field and check for any characters apart from the allowed list : [a-zA-Z0-9\-]
• Post validating, upload the configuration file again and retry the deployment.
