Error 403 on Android

None of the tiles in my app are visible anymore and i only see the error 403 info. It worked fine a couple hours ago. Can someone let me know what i can do? I need this for a project at uni using AndroidStudio and i need to present it on Tuesday.

Please help and thank you.

Which app are you using and what’s the source (URL) of the tiles?

Does this link help?

no, not really

mapView.setTileSource(TileSourceFactory.MAPNIK);
i am working in AndroidStudio and i used osmdroid and osmbonuspack from git

apparently your program violates Tile Usage Policy

you may need to change your code, possibly fixing how you use library or exchange it for a different one so its requests start following Tile Usage Policy rules
