SOLVED! at least for me. *after 2 days of marionberry error...FINALYYYY **If you want the solution directly, skip the pharagraph So I watched this youtube video https://www.youtube.com/watch?v=iA7fpOa4u0c but the 'fix' doesn't work. I went to the comment section and I noticed the channel owner posted "remember to close your discord" . Then I wondered "why an app would make any difference" mainly cause marionberry is LOCAL NETWORK related issue. So I tried experimenting few things and this works BEST on FIRST TRY: 1. CLOSE(through task manager) ALL NETWORK RELATED APPS (worth experimenting if you dont know) *MINE I ISE ADBLOCKER APPS WHICH IS ADGUARD... I CLOSE IT AND DESTINY IS GOOD TO GO 2. PROFIT Disclaimer: 1. Result may vary 2. What I ALREADY did: basically ANYTHING that you can find as the solution on the internet ( clean installation, change network setting,etc...) Goodluck!

My story is similar, except I can log in. The problem happens when I go to launch any activity. I get a different error code depending on what I try to do. The first Shadowkeep mission is HYENA, tower is ELDERBERRY, etc.

Im too having this damn error on the steam version after i transfered from bnet. Its crazy, i did everything and it still pop out..

Me...and it's driving me mad - disabled all firewalls/av/malware Rebooted router - nothing. Only thing that resolved it was doing it via GeForce now. Seems to be no resolution for it anywhere?
