Many Thanks TenPatrol,
ISSUE FIXED !
You are right ! The “hosts” file had been modified by the “MSFS Map Enhancement” addon that I had installed from the “flightsim.to” site !
This piece of software adds the following mappings in the “hosts” file :
127.0.0.1 kh.ssl.ak.tiles.virtualearth.net
127.0.0.1 t3.ssl.ak.tiles.virtualearth.net
127.0.0.1 t2.ssl.ak.tiles.virtualearth.net
127.0.0.1 t1.ssl.ak.tiles.virtualearth.net
127.0.0.1 t0.ssl.ak.tiles.virtualearth.net
127.0.0.1 khstorelive.azureedge.net
127.0.0.1 cdn-shared-wca-endpoint.azureedge.net
127.0.0.1 sunriseworld.akamaized.net
If for any reason you reboot your system without havig stoped “MSFS Map Enhancement” then you are stuck with the issue !!! 
I used :
to clear the mess.
Best Regards.
