    Error message

    bsock.c:237 gethostbyname() for host "XXXX" failed: ERR=Authoritative answer for host not found.

    Error description

    This error indicates that the IP address of the client (see in Clients › Edit) is not resolvable. By default, the Backup & Disaster Recovery appliance uses the client name as the address, and this field needs to be adjusted.

    Steps to resolve

    This error can be resolved in two ways:

    • Verify that the host name is resolvable via DNS, and make adjustments as needed.

    • Change the address to the IP address rather than the host name.
