Some users encountered the error just after installing the game. Before moving on with the troubleshooting process, restart your system/networking equipment and then check if the game is clear of the error.

The issue could be caused by a temporary malfunction of the communication/application modules. In this context, restarting the download of the updates may solve the problem.
Solution 2: Try Another Network

Solution 4: Disable Single Output of Multi-GPUs (SLI and CrossFire)
