Check Shadow Updates

  • Visit Shadow's status page to see if your server is under maintenance. We recommend checking the server nearest to your location for reference.
  • See the #annoucements channel on Shadow's Discord server to see if a community manager or moderator has posted any updates, or see if other users are experiencing the same issue.

If there are no updates related to the error, continue to the next section being sure to test your connection between each one.

Connect to a Different Network

Connect your device to a different network or use a different device. To do this, switch to another WiFi or 4G network, or use a smartphone or other device available to you. Try starting Shadow after you've applied these changes.

Troubleshoot Your Internet Connection

Complete the tasks listed below until the issue is resolved. If you are not able to complete a task, proceed to the next item.

  1. Disable your Antivirus, Firewall, VPN, or proxy.

  3. Reset your modem.
  4. Disconnect any Ethernet cables from the modem, then turn off modem.
  5. After 60 seconds, turn on the modem and monitor the lights on the front. Fewer lights generally indicate a problem with the modem.

Troubleshooting #2 - Shadow R:300/R:301 errors


In some cases, shutting down Shadow will resolve the issue. To shut down Shadow, click the Help (?) button located in the Shadow launcher, then click Shut Down Shadow.


If Shadow does not start after shutting it down, try starting Shadow from a newer device. If Shadow starts, it's likely the older device does not meet our minimum requirements and cannot run Shadow.

To confirm your device meets our minimum requirements, choose your device's operating system below:

  • Windows
  • MacOS
  • Android

If your hardware meets or exceeds our minimum requirements, send Diagnostic Logs to Shadow Support for assistance.

R:302 - Video decoding error

  • Disable the "low connection " mode in the application settings  
  • Make sure your local machine is up to date (OS, driver ...)
  • Update the graphics drivers of your local machine.

If none of these work, please reach out to Shadow Support.
