Failed to query host x.x.x.x information, provide correct host IP address and make sure VxRail Manager can connect to the host.

When i did manual add vxrail nodes from vxrail manager setup . This issue appeared.  "Failed to query host x.x.x.x information, provide correct host IP address and make sure VxRail Manager can connect to the host."

vxrail manager can ping to those vxrail nodes . 

Could you please give any suggestions ? Thank you everyone.
