Trial License Download Fails

I get the following error when the system tries to download a trial license:
ERROR 2020-07-31 13:53:29,962 [main] com.complexible.stardog.StardogLicense:main(416): Error during trial license retrieval: java.net.UnknownHostException: reginaldstardogblue.stardog.com: Name or service not known
Perhaps it is due to firewall issues. Is there another way I can download a trial license?
