Error message "Cannot connect to license server system (-15,570:113 No route to host)" or "Unknown host: <hostname>"

• Check that the hostname in the licensefile is also listed in the /etc/hosts file.

The /etc/hosts file looks something like this:

127.0.0.1 localhost.localdomain localhost4
::1 localhost.localdomain localhost6

Add the name of your license server to the end of the lines, so that they look like this:

127.0.0.1 localhost.localdomain localhost4 myservername
::1 localhost.localdomain localhost6 myservername
 

• If the above solution doesn't work, try to change the hostname in the licensefile to localhost and add the line 127.0.0.1 localhost in the /etc/hosts file. It is also possible to get a hint of what is wrong by using the command /usr/sbin/ping hostname.
