Usually the issues with PVS revolve around the url and associated network security such as DNS.

Make sure with VBox that you leave the settings in the VM to be host only, best not to try to change to Bridged or other settings as there are known issues with these that involve editing files in the PVS image to fix.

Next, the url should be whatever is shown in PVS (not the samples in the instructions if you have downloaded those, as the url's vary for different courses:

I have checked with the CSSA PVS image and the url should be "http://prpc:8080", not as posted in your question.

Also, if the friendly url doesn't work, please replace prpc with the IP address as shown inyour PVS screen. To see what it is, log into the PVS session with user id: "architect", password, "password",

it should be something like "http://192.168.56.101:8080", but may vary depending upon your system.

 As one of the most common issues we face is where local network security, DNS servers etc will block the friendly url.

If in doubt, also try disconnecting from any corporate network while initially connecting to see if this is the issue.

Finally please note, post course questions in the appropriate forum, as you will most likely get a better response rate, also check the course specific forum before posting as most likely there will be existing answered posts to look at for help. There is a CSSA forum for CSSa course questions (link in the course screens for easy access)
