Ah, thanks XnL! I switched to 15859 and there they are! :-D

Thanks for all the effort and bringing Maxar back to us!

However, there’s maybe still some waitingtime before JOSM picks it up again? I updated to 15806 but the Maxar tiles don’t showup. (I can see Bing of Esri.)

And Googling on the error I got, well, even Google has no idea.

Anything I missed or I should do?
