    [OFFICIAL] Basic Launcher Troubleshooting

    Make sure to check our Launcher Support Knowledge Base at to see if your issue has already been documented.

    As a general rule, we also suggest the following general troubleshooting steps:
    • Try cleanly reinstalling your GPU Drivers. To perform a clean GPU driver installation:
      • Locate and download the latest drivers for your GPU.
      • For AMD GPUs go here:
      • For NVIDIA GPUs go here: -Uninstall your current GPU drivers through Add/Remove Programs.
      • Reboot your system.
      • Locate and run the downloaded installation package for your GPU. Please perform a minimal/custom installation and install the GPU drivers only.
      • Reboot your system.

    Some users find that software utilities such as "DDU": helpful to clean out all of the remnants of an old driver installation. However, this is generally not required.
    • Try our network troubleshooting steps to make sure there's not a problem with your connection:
    Many issues with Epic Games products can be caused by network connectivity problems. If you suspect that you may have a connectivity issue, please try all of the following steps:
    • Make sure you are using a Broadband internet connection.
      • Between 2010 and 2015, the FCC defined a Broadband connection as 4 Mbps download/1 Mbps upload.
      • After 2015, the FCC defined a Broadband connection as 25 Mbps download/3 Mbps upload.
    • Make sure you are not behind a proxy and do not have filtered.
      • If you are behind a proxy, add an exception for (or ask your IT department to do so).
    • Ensure that ports 80, 443 (https), and 5222 are unblocked.
      • Navigate to Control Panel> System and Security> Windows Firewall.
      • Click Advanced Settings.
      • On the left, select Inbound Rules.
      • On the right, select New Rule...
      • Select Port, then click Next.
      • In the text box beside Specific local ports, enter 5222, 443, 80, then click Next three more times.
      • In the Name box, enter UE4, then click Finish.
    • Try switching your DNS Server (OpenDNS or GoogleDNS)
    • Try rebooting your router and modem.
