Troubleshooting Network Connectivity
Description When starting the Symphony Math program, the 'Please wait...' message appears and stays onscreen for an extended period of time. An error message may appear with a numbered 'Network Error'.
Step 1: Ensure Student Access to the Symphony Web Servers

Symphony Math stores student data on secure internet servers. If your school has internet filtering software that restricts access to internet sites, you will need to ensure that the Symphony data servers are allowed access to and from student workstations.

The Symphony Math student program must have access to the following URLS:

  • https://qs1221.pair.com (IP address: 216.92.2.55)
  • https://qs1575.pair.com (IP address: 216.92.127.114)
  • https://admin.symphonylearning.com (IP address: 216.92.223.130)
  • http://www.symphonylearning.com (IP address: 64.130.42.165)

Add the URLs above to your 'acceptable' list of URLs to allow student data to be sent to and from the Symphony Learning servers.
Step 2: Check Proxy Server Settings

Proxy Server software is used within networks to control internet access to and from different users and software. If your school network uses a Proxy Server, settings must be input from the "Network Settings" tab within the Settings Control Panel in Symphony Math. Most likely, you will have to consult with your network administrator to get the details on your Proxy Server.

The Network Settings tab is the middle tab, and allows input of Proxy Server Address, Port, Username, and Password to be set. Be sure to press Apply after you enter this information. If you are unsure of your proxy server settings, try selecting the 'Use Proxy Server' checkbox, leaving the other settings fields empty. When settings are applied, the computer's default proxy settings will be used.

Step 3: Clear SSL and Certificate Data

It may be necessary to clear the SSL state in order to delete old and/or erroneous information on secure sites.
