MAP SYNC Failed

I am at a new location. I have got the GPS fix. The map is showing blank. So I choose the option that says download map.
When the watch is connected to the power outlet at the wall plug, it starts to sync YouTube music and then the map.
At 100% it says map sync failed.
1: I have reset the watch to factory. First connected to laptop to garmin express, entered user id password . Updated the middle east and chine topo map via pc.
2: connected the watch and sync with my phone.
3: map+ subscription is active.
On the map manager it still says update available
How can i sync the maps via wifi on the go without getting the error MAP Sync Failed?
Thank You
