So my issue (after two months) has been resolved!! 
Low and behold it was in the Host file within Windows system folder itself. The actual location is C:\Windows\System32\drivers\etc.
I found that removing the following entries in the file resolved the network issue with FS2020
127.0.0.1 kh.ssl.ak.tiles.virtualearth.net
127.0.0.1 khstorelive.azureedge.net
If you ever have a Window that informs you "Your connection had an issue while streaming data, you have been switched to offline mode”, you may want to check the Host file.
