When I click the course, I receive this error message: “Unable to communicate with the server. Exit, Retry” Whats wrong?
In order to retrieve/save your previous/current progress information, the course needs to communicate with the servers to maintain your progress. The message indicated that the communication cannot be established. The followings are the most common causes of the communication problem: • Firewall – Both Network and local firewalls (hardware/software) could potential block the communication. Please consult with your network administrator or firewall manual how to alter the permissions. • Pop-Up blocking programs (e.g. Ad Aware) – Pop-up blockers tend to block any access to the outside that are not initiated from current browser. Please check with your program’s manual how to alter the settings or temporary disable the program. • Chat programs (e.g. messenger) – Some security settings on the chat programs may block the communication. Please temporarily disable the chat programs and try the course again.
