I've noticed that when I create a server adapter and I give it an IP address as the hostname, the hostname remains the default value, ie, localhost.
This is annoying in the case where I want to connect to a VM running on my own host (eg, a VM running Docker). In this particular case, I set the hostname at something like 192.168.99.100 but it is reverted as localhost which gives 127.0.0.1 as the primary IP address. As a consequence, the server adapter fails to connect to the server since it uses the wrong IP address.

Note that the host name can be changed for good in the Server Configuration Editor after its creation.
