Restart the Marathon application to generate a new authentication token. Post-restart waits are usually brief.

Step-by-Step Fixes

  1. Fully quit Marathon (Force close on PS5/Xbox; quit from Steam on PC)
  2. Wait 30–60 seconds
  3. Relaunch Marathon
  4. [PC] If it repeats: run ipconfig /flushdns in admin Command Prompt, switch to wired Ethernet, then retry

What Causes W:8:80090305?

W:8:80090305 occurs when the Marathon client's authentication handshake does not complete within the server's allowed time. Bungie's servers limit how long they wait for each connection. During Server Slam and launch, queues back up and time limits get hit. A restart clears your session and gives you a fresh token.
