Reach not reaching solid Green led

One of my Reach boards gets stuck in the flashing Green/Yellow stage, never turning to solid Green. It means that I have no way to access it.
Any suggestions?

What version are you running? (Reachview and image)

Both the latest. All worked well, it suddenly started to behave like that. My 2nd board with the same SW works fine.

If it doesnt create own hotspot or not connected to other wifi and not accessible in any way, i would try reflashing it.
