Same issue. Stuck waiting for security scan. Spent hours trying to figure out what I missed.... So frustrating, EA no help?
OK so I finally was able to finish the quest. Here are the steps I took, hope this helps others.
I left the planet, and came back. Went to the flophouse and started engaging all the scavengers. Worked my way all the way to the top to the far east building (You can turn off the alarms if you want). There is no marker for this on your map, once you approach the correct building SAM will talk about hacking the security. Inside the building there are 2 terminals, one of them you "hack" which starts a wave of enemies. Once complete the bottom building is unlocked and you can proceed with finishing the quest. As soon as the quest completed I got an updated quest to build the outpost. I believe the bug is that you can complete the Remnant core quest before engaging this side of the flophouse, which is what I did. That door should be locked until this is completed to prevent this from happening.
I followed this to make sure I was not missing anything. Hopefully this helps other out with this bug.

Very frustration EA, I spent 4 hours trying to figure this out with 100% viability on Elaaden. Please fix this quest.
My fix for all quest bugs(so far) has been to walk about 100m away,save game,exit game.Re-load game hit Resume,go back to problem area and its fixed.
This has worked every time for me
81% viability I do not know if is same issue, but I know I have the settlement Icon on the planet, and I can not activate it. I have walked all around it, and approached it from every direction, but it will not bring up the click thing, and let me activate it.
I have the same thing on Kaldara, 74% viability, and no matter what I do the settlement will not allow me to click on it. I have cleared the cave with the Kett in it. where Sloan shows up to supposedly help.
My Hours playing are racking up because of this,but they are not actual playing hours, just wandering around Hours, trying to figure out why the game will not advance... it is troublesome.. to the maddening rage state.
Confirmed. Leaving planet coming back and FULL clearing (to find where you messed up) and SAM will set you straight.
