Connect to the client again (again, r-v will ask for the password in a pop-up window):

 bash$ remote-viewer --spice-ca-file ${CA_FILE} --spice-host-subject "${SUBJECT}" spice://${HOST}/?port=${PORT}\&tls-port=${SPORT}
 

Now, the question is.... What's the password? Or where can I find it?

Kind regards,

Koen
