Kiava Gamma Cyberguard Access Code

[Razer]

On Kiava Gamma at the moment and exploring. Went to a Cyberguard Cogitator which asks for an access code I don't have. Reading online this is done through visiting the Fireborn vessel? But I've done that already. Also completed Heinrik's questline. That all didn't help. It seems there's lots of loot after accessing this cogitator, but I cannot access it. Anyone know what to do?

I think I understand what's happened. Either I did something wrong during the Fireborn event, or Idira is supposed to do something, but I killed her so she aint doing anything. Nevermind. I can't access this area with tons of loot. Meh.
