Check your network configuration to find any issues with your firewall, router, or port settings.
- Reset your network devices to make sure your router hasn't become flooded with data.
- Run your console's built-in connection test (Playstation 4/Xbox One).
- Use your console's internet browser to run a Looking Glass test. This will help determine if the problem is between your console and our servers.
