Troubleshooting

The SFN application cannot connect to remote T-Mobile servers

Neither the primary nor the secondary server is accessible. Please check whether you are connected to the internet.

 
Possible causes:

• The connection is blocked by the firewall system in your company
  Please ask the administrator of your firewall system to enable internet connection to IP address 62.141.3.77, port 443 (https://sfn.t-mobile.cz/sfn) for you. You can check whether this IP address is enabled in your company by specifying the https://sfn.t-mobile.cz/sfn/hello URL into your internet browser. If the connection is enabled in your system, the following code displays after a few seconds:
  <?xml version="1.0" encoding="UTF-8" ?>
  - <sfnServlet>
  <version>1.5</version>
  </sfnServlet>
• The connection is blocked by the proxy server in your company
  On the application settings page which is available after selecting Application Parameters -> Connections from the menu, please check the “Use proxy server” box and fill in the appropriate fields with parameters supplied by your network administrator; you can also copy the required data from your browser settings page. In Internet Explorer, this page displays after selecting Tools -> Internet Options from the menu, clicking on the Connections tab and then on the LAN Settings button. The required parameters are displayed in the Proxy Server area of the page.
  If your proxy server requires authentication through username and password, please check the “Proxy server requires authentication” checkbox in the SFN II settings. We recommend that you leave the Username and Password fields unfilled so that the application can use these data from your Internet Explorer configuration.
