Can you check if the client’s computername (in the client settings) equals the clientname on the server?

The current client/server combination has two issues with internet clients that I have recently discovered:

The computername set by the server in the downloaded client gets reset by the server if it was not set in “Settings” (On the server). The client then uses its hostname to try to connect to the server.
The Server does not correctly log failed authentications where the client does not exist. It logs “No Authentication key” instead.
