Thanks. It worked in the end. The syntax was not clear. However I want to move my data to the EU. That's why I tried eurosky.social (and it worked). But I am still a bit perplexed on them. It's less European than one might think, as they are funded by Free Our Feeds, which relies on a U.S. fiscal sponsor (Exchange Point Institute, a U.S. 501(c)(3) nonprofit). I tried getting more transparency but they remain rather vague.
