geodata::elevation_3s() function currently points to non-existing URLs:

elev <- geodata::elevation_3s(lon = 56.42, lat = 58.07, path = ".")

I updated the URL with what is currently working on CGIAR. The fallback URLs are also failing in the current version, but I don't know what to replace them with.
