Can’t make it show the kml or gpx

Hello, great plugin so far! But I can’t see the route files on a map.

The files are here:
https://aguerrilha.pt/kml/cozinharute/palmela/gpxpalmelaandre.gpx
https://aguerrilha.pt/kml/cozinharute/palmela/palmelaandre.kml
https://aguerrilha.pt/kml/cozinharute/palmela/palmelajen.kml

I tried to create a page and insert the shortcode:
[geo2 xmlurl=https://aguerrilha.pt/kml/cozinharute/palmela/palmelajen.kml]

or without the https

[geo2 xmlurl=https://aguerrilha.pt/kml/cozinharute/palmela/palmelajen.kml]

or with a route id

[geo2 route=1 xmlurl=https://aguerrilha.pt/kml/cozinharute/palmela/palmelajen.kml]

but nothing…
Can anyone give a hand?

The page I need help with: [log in to see the link]
