  Hi there,

  Thanks for reaching out! 

  This sounds like a connection issue of some kind is occurring and could be an internet service provider issue.

  Below are suggestions that may help with your issue:

   

  1. Please review our Network Troubleshooting Guide for best optimizing your connection to Marathon.
  2. Our Network Setup guide provides recommendations and internet connection requirements.
  3. We offer troubleshooting steps in our Error Code guide for those receiving the same or several error codes.
  4. To best optimize your connection and improve your latency and packet loss, please view our Optimzing Connections guide.
  5. You may need to power cycle your router or modem by following the device manufacturer's recommendations.
  6. There can be common network hardware issues that interfere with each other. Please view our guide for troubleshooting steps.
  7. It's also possible that you need to enable IPV6 or IPv4 on your device, too.
  8. If you still experience issues after going through the troubleshooting steps above, you may need to adjust your router's or modem's settings. Please review our Advanced Networking Steps guide for other possible solutions, such as enabling UPnP, changing your NAT type, or opening up specific ports.
  9. It may be beneficial to clear your platform cache: PC players can perform this by viewing Steam's article
  10. You may need to quit all other apps on your PC when playing Marathon, including turning off other connected devices that are streaming media.
