Destiny 2 Nightingale error [Solved!]
Thursday, February 22. 2018
As an employee of (a subsidiary of) Activision/Blizzard, last year those who wanted, got keys for Destiny 2.
It never worked! I never go to play it. 
On game launch:
... and BANG! The dreaded Nightingale error:
For past couple of months, that's how much I saw Destiny 2. That isn't much. Darn!
Actually, there is an Internet full of people having the same problem. There are various solutions to, which have worked for some people and for some, not so much.
After doing all the possible things, including throwing dried chicken bones to a magical sand circle, I ran out of options. I had to escalate the problem to Blizzard Support. Since this wasn't a paid game, obviously it didn't reach their highest priority queue. But ultimately the cogs of bureaucracy aligned and I got the required attention to my problem. But ... it was unsovalvable. Or it seemed to be one.
Today, after escalating the problem back to Bungie, they pointed out the problem. My computer didn't manage to reach their CDN, so the game got angry and spat the Nightingale on my face. They also hinted me about what my computer did instead and ...
Somewhere in the guts of the Destiny 2, there is a component reading the value of environment variable HTTP_PROXY. I had that set on the PC because of ... something I did for software development years ago.
After deleting the variable, the game started. WHOA!
So, it wasn't my router, DNS, firewall, or ... whatever I attempted before. Problem solved!
