Google Nexus 5X won't security update

I have 2 Nexus 5X (LG Nexus 5X 2016) with Oreo 8.1.0
My work phone has security update january 5th 2018.
The main private phone is stuck on the november 5th 2017 security patch.

I've tried factory reset with no luck.

Are the two phones on the same network? Some seem to be slower with updates than others; Google's own Project Fi - strangely enough - seems to be slow to push updates...

If it is possible, try to switch sim cards. Off course only if they are from different provider.

You could try sideloading it. Here's a link.

See the "Flashing an OTA update image" section".

Edit: I just did a sideload of the Feb patch. It only takes a few minutes.
