Does this only occur in Firefox?

Try the following:

  1. Go to Firefox options
  2. Go to the Advanced tab
  3. Select the Network tab from this tab
  4. Under the Connection section, click the Settings... button
  5. Select Use System Proxy Settings

Please report back soon.


If the issue occurs on other browsers, try the following:

  • Ensure the internet router/cable is connected to your computer and internet plug
  • Check your computer's DNS settings
  • Scan your computer for viruses, malware and bad registries
  • Contact your internet provider for more assistance

Check the connection settings.

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
