The error: ""This LON-CAPA server is temporarily not available for  
login" originates in /home/httpd/lib/perl/Apache/lonlogin.pm and  
occurs when LON-CAPA fails to successfully store token information  
generated when displaying the standard LON-CAPA log-in page.

This can occur in two ways:

(a) The LON-CAPA Host ID of the machine does not map to a hostname.

In this case you'll find a message: "No valid logtoken for log-in page  
-- unable to determine hostname for hostID: <Host ID> Check entry in  
hosts.tab" in /home/httpd/perl/logs/lonnet.log

or

(b) The LON-CAPA daemons are unable to sustain a connection on the  
local machine (i.e., lonc on the server/VM itself fails when  
connecting to lond on the server/VM itself).

To fix (a) check that you have the correct information for the  
LON-CAPA server in /home/httpd/lonTabs/hosts.tab

For (b), take a look at:
ps aux |grep lond
ps aux |grep lonc

sudo /etc/init.d/loncontrol restart
sudo /sbin/service apache2 reload

should fix things.
