New Post: Tile provider problem

Hi,
I'm setting tile provider for my map. some of providers work fine but some of them not working. for example GoogleTerrain work fine but GoogleSatellite not show some of places. First I think that source of this provider not show some of places but when I use another map manager (for example QGIS) it works fine. anybody know whats the problem?
In addition when I log the requests of providers I see that the Bing providers not send any requset and log is empty. why not set URL for this provider?
