Solution
Please ensure that your server can accurately resolve the domain name 3.license.getisymphony.com. This is usually a DNS issue on your server or network. To verify from a Linux shell whether you are able to resolve the correct domain, use the following command:
$ host 3.license.getisymphony.com
If the above command returns an error, such as "Host 3.license.getisymphony.com not found: 3(NXDOMAIN)", then your server is unable to correctly resolve the domain for the licensing server. You will need to correct the DNS issues to be able to activate your iSymphony license.
