===== Issue 1: =====



The error occurred when upgrading Control (CHAPI). 

**Cause**



The cause of this error was due to a TCP port being blocked by a hardware firewall. The TCP port will need to be open to allow communication to and from the Cyrious License Manager API.



Note: The TCP port and URI to the Control License Manager is restricted information. Please contact Cyrious Software Support for more information.



==== Resolution ====



Determine if a hardware or software firewall is in place that is blocking TCP ports. If so, open the TCP ports being blocked.



Note: For added security, contact Cyrious Software Support to obtain the URI and port to bind the communication to. Cyrious Tech's see this [[http://internal.cyriouswiki.com/error_retrieving_license_information|link]].
