Hydra on Kali Linux VMware machine

When I try to use hydra from Kali Linux to a CTF vmware image, where both kali and the image are connected via host only adapter I get an error.

This is the command I execute:

hydra -t 4 -l amy -P /usr/share/wordlists/wordlists/top10000.txt ssh

The password is in the word list.

The error states that 2 targets could not get resolved or connected and that 4 targets did not complete.

What am I doing wrong?
