Hello and thank you for your interest in this Actor!

Our web-scraping library Crawlee is indeed having some issues with processing the sitemap on this domain. I already created a GitHub issue for this (see here) and our team will look into this soon.

In the meantime, you can simply disable the sitemap discovery (the Consider URLs from Sitemaps) option for this run. This way, the Actor won't try to access the sitemap and won't fail. Keep in mind that the sitemap discovery is only a supportive mechanism (and in most cases, you should get the same results in the same amount of time with and without it).

I'll keep you posted with any updates regarding this issue. Thank you! (and sorry for the inconvenience.)
