Lightroom: Map module keeps flashing "map offline"

I have started seeing new behavior in the maps module in LR. Every time I zoom or navigate the map or try to link a photo to a location, I get a world map in grey and a message at the bottom 'Map is offline'. Then the map reverts to the regular map.

What has happened and how do I correct. Could you help me please. This is incredibly annoying
