Unable to connect to tracker or peers
If the Blizzard Downloader displays an error message that reads "Could not connect to tracker", this means that the downloader was unable to open an http connection to the tracker over TCP ports 3724, 6112, or 6881-6999. This can happen if the computer is not currently connected to the Internet, or if outgoing traffic on these ports is blocked for some reason.
Below are some possible solutions.
1.
Firewall Configuration and Troubleshooting*
If you have a firewall, be sure that it is set up to allow for outgoing connections on ports 3724,6112, and 6881-6999 for the TCP (also called TCP/IP) protocol. More information on how to open ports for some popular firewalls can be found on our
Firewall configuration pages. If your firewall is not listed there or you need more help, please refer to your firewall documentation or contact the manufacturer.
Important note: Please be aware that many popular firewalls will become very restrictive to traffic when 'disabled', including shutting down all traffic on some ports. Please be sure any firewalls you have installed are enabled and configured correctly in order to use the downloader effectively.
2.
Internet Service or Network Provider Issues
You may wish to contact your ISP or network provider to make sure that they are not blocking http connections on TCP ports 3724, 6112, and 6881-6999. Some corporate or campus networks may have a restriction on what traffic is acceptable. In the event of such a restriction, you may be redirected to a direct download. Due to the nature of direct downloads, you may experience a slow transfer if redirected in this way.
3.
Closing Background Applications
Try the instructions on our
Closing Background Applications page, then try restart the downloader.
