Multiple errors: YAM, NIGHTINGALE

Xbox account: Seshdel Bungie account: Seshdel#0438 My Region: Russia, Moscow Subject: Persistent Connection Errors (Nightingale / YAM W:8:00002EE7) on Xbox – Extensive Troubleshooting Already Performed Dear Bungie Support Team, I am writing to report a persistent and game-breaking connectivity issue I have been experiencing in Marathon on Xbox. I have been unable to play the game for two weeks, and the error codes have shifted over time without any change in my network environment. Issue Timeline: 1. Initial Error: The problem started with the Nightingale error code. 2. Current Error: After several days of trying to fix the Nightingale error, it changed to the YAM error. 3. Current Specific Error: I am now stuck on a red screen stating "Marathon servers are unavailable" with the code YAM and additional information W:8:00002EE7. Troubleshooting Steps I Have Already Taken (Without Success): I want to emphasize that I have performed extensive troubleshooting, ruling out local hardware and general internet issues: · Network & DNS: Changed DNS settings multiple times (tried Cloudflare 1.1.1.1, Google 8.8.8.8, and others). · Internet Connection: Tested the game on a completely different network (mobile hotspot via phone) to rule out ISP or router issues. The error persists on mobile data as well. · Power Cycle: Performed a full power cycle (unplugged the Xbox from the wall for 10+ minutes, pressed the power button to discharge residual electricity). · Game & Console Reinstallation: Fully uninstalled and reinstalled the game. I also performed a full factory reset of my Xbox console. · Account & Profile: Cleared the Alternative MAC address in Xbox network settings. Logged out and back into my Xbox profile. I also tried deleting local save data for Marathon. · Language/Region: Changed the game language and console region settings. · No Antivirus: I am on Xbox, so there is no third-party antivirus software running, which is a common PC-related cause for this error. Additional Context (Account Issues): I also experience regional account login issues on my Xbox. When trying to sign in, the account sometimes fails to connect, which makes troubleshooting DNS settings extremely difficult. I suspect this might be related to the persistent YAM error, as it affects the sign-on process. Request: Could you please investigate this on your end? I have exhausted all possible local troubleshooting steps. I would like to know: 1. Are there any known issues with the YAM error (W:8:00002EE7) for players in my region? 2. Is there a possibility that my account is flagged or blocked on the server side, causing these connection failures? 3. Are there any specific ports or advanced network settings I should try that I haven't already? I love this game and really want to play it. Any help would be greatly appreciated. Thank you for your time and assistance. Sincerely, Alexander seshdel@yandex.ru
