Here2+ (M8P) no fix

I am using a Here2+ as base flashed with firmware almost a year ago 1.43REF
I am pretty sure it worked before, now it does not get a fix.
Tried to re-flash it, assuming the device itself is working fine (I can read config/set config, flash it)… but it never spots even one satellite.

Are there some magic settings that need to be set?
I’ve even tried the “autoconfigure” in mission planner.
