Hi @VDSB ,

The first message (1.PNG) is a "Warning" for the user to accept and trust the target before trying to establish the connection with the target from SHD (This is to ensure the target is trusted by the user), in this step, you can either "Accept" or "Cancel" depending upon the target trust information shown.

For the second error (2.PNG), it appears to be the network configuration problem, so here SHD is unable to resolve the hostname of the target, can you please check is nslookup from SHD VM to the target is resolving the hostname correctly, if not please check the network settings file.
