Can't connect to the network after configuring my third-party client

If you're having problems connecting to the Google Talk service using a third party chat client, you may have network restrictions in place. These are typically created by security or firewall software on your computer, or network firewalls.

You can find out whether your network allows a connection to the Google Talk service by running a telnet test.

If you use Windows:

  1. Click the Start menu in your system tray
  2. Select Run...
  3. Type cmd and click OK.
  4. At the prompt, type telnet talk.google.com 5222
  5. Press Enter.
  6. If the screen clears to a blank screen, your Internet connection is ok. If the the screen didn't clear and you get a connection error, it's likely that firewall or security software on your computer or network is blocking your Google Talk connection.

If you use a Mac:

  1. Click the Macintosh Hard Drive icon and open the Applications folder.
  2. Open Utilities and select Terminal.
  3. At the prompt, type telnet talk.google.com 5223
  4. Press Enter.
  5. If a message appears stating, 'Connected to talk.l.google.com,' your Intenet connection is OK.  If the telnet command fails to connect, it's likely that firewall or security software on your computer or network is blocking your Google Talk connection.
