After going through the solutions that were the most effective in our testing, we came to the conclusion that the following are the most important reasons behind the occurrence of this issue.

  • DNS Configuration: In certain cases, the DNS configuration that is being used on the Xbox, PS4 or the PC might not have been set properly and due to this, the Battlefront 2 Error 1017 might be getting triggered. Therefore, we suggest that you configure this DNS address properly.
  • Firewall/Antivirus: The Firewall or the Antivirus installed on your computer might be blocking the connection from being made with the server. Therefore, we suggest that you try to block this temporarily and check to see if doing so fixes the error.
  • Outdated Windows: If Windows has been outdated on your computer, the connection might not be properly made due to which the error occurs. Therefore, we suggest that you update Windows to the latest available version and check to see if the issue is fixed.
