Error 403 when add overlay https://strava-heatmap.tiles.freemap.sk/sport_MountainBikeRide/hot/{z}/{x}/{y}.png

[ravenfeld]

I've added this card which works on the JOSM application and I've checked with POSTMAN that it works but with gpxStudio I get a 403 and I don't really know why.
If you could help me.

Then, if you've answered my request to manage heat cards directly for certain sports, close the ticket ;)
