Nightingale to weasel, tried everything plus what is on youtube

I am unable to launch into a match of Marathon while attempting cross-play with friends, despite my local network and Bungie's servers functioning perfectly for Destiny 2.

  • My Platform: PC (Steam)

  • Teammates' Platforms: PS5 (Two players joined my fireteam lobby)

  • The Trigger: The issue occurs immediately upon hitting "Run" to initiate matchmaking, while the game is actively loading and connecting.

Error Progression & Symptoms

  1. First Attempt: Received Error Code: Nightingale during the initial load screen.

  2. Second Attempt: Immediately hit with Error Code: Weasel upon trying to reconnect.

  3. Subsequent Behavior: Persistent connection failure strictly within Marathon.

Troubleshooting Already Completed

To isolate the issue, I went through the official Bungie Help Guides and community resources, executing the following steps to no avail:

  • Followed all steps in the official Network Troubleshooting Guide (including flushing DNS and power-cycling network hardware).

  • Verified integrity of game files on Steam.

  • Completely uninstalled and cleanly re-installed Marathon.

Cross-Game Isolation Test

To verify if this was a localized hardware, account, or ISP issue, I launched Destiny 2 on the same PC and network:

  • Result: Destiny 2 loads completely normally.

  • Observation: I am able to freely navigate public spaces (the Tower) and utilize Bungie's live servers without a single error code or disconnection.

Request

Given that my network connects flawlessly to Bungie's Destiny 2 infrastructure, why am I experiencing persistent, game-breaking network errors (Nightingale/Weasel) specifically when initiating cross-play matchmaking in Marathon? I need technical insight into what is blocking this connection or if this is a known cross-play routing bug with Steam-to-PS5 lobbies.

    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, and console players can do this by following the steps outlined inside each platform's section in our support article.
    10. You may need to quit all other apps on your PC or console when playing Marathon, including turning off other connected devices that are streaming media.
