I get this error on saving a long track (from France to North cap) :

 Sorry, the route wasn't saved because an error occurred: Bad Gateway

Is it because the track I like to save has too many data to be saved ?

Add a Warmshower Layer

Hi,
Thanks for this amazing work !
I was wondering if it was possible to add a Warmshower Layer on the map when looking for overnight place ?

I don't know if Warmshower has open source data, but this could be great !

Best regards
