You got to finish the ENTIRE Wastelanders questline.

Oh

Ard you on the quest?

No, i just went there on my own cos i saw my friend with the armor and he told me the name of it, so i just googled how to get it and followed a guide to get vault code

And i dont even know if any quest is tied to entering it

You have to follow the main overseer quests to get in.

Just to make sure I'm doing the right one, does the quest eventually lead you to talking to settlers and raiders, then choosing a side?
