Restart your network hardware
1. Turn off your PC/Console and your Modem/Router and wait for 15 - 30 seconds.
2. Fully power up your Modem/Router. (It may take a couple of minutes to re-establish your connection.)
3. Turn on your PC/Console and test the connection of your game again.
At this point, if you still have trouble then you may have a firewall interfering with your connection. Please configure the following network ports within your router from your PC:
TCP and UDP: 80, 443
Directions for configuring network ports are specific to the hardware being used and can be found by visiting the manufacturer's website.
DMZ (Console only)
If this does not solve your issue, try placing your console in the DMZ of the router or establishing a direct connection to your modem (where available) and retry.
Traffic throttling / Blocked ports
There may also be certain restrictions set by your Internet Service Provider (ISP). If you continue to have trouble, please contact your ISP for details on any specific restrictions on the previously mentioned network ports.
