Support > Orion Desktop Support > Software Installation > Troubleshooting > A firewall may be blocking network connections from Orion

For security reasons, network administrators often block access to unknown servers on the Internet. For Orion and Athena, this may cause a problem because they each communicate with Internet servers to report scores online, perform security checks, and to obtain information on new software updates. if you are having issues, please use the Network Port Tester to test your network.

Depending on the network firewall's setting, if Orion cannot communicate, the error may be one of a number of different things, including:

•Unable to communicate with the remote server.

•Unauthorized.

•The remote server returned an unexpected response.

•Your computer's time is off by more than five minutes.

To resolve these problems, please ask your network administrator to allow the following communication. If he or she has any questions or concerns, please have them contact us directly.
