Knowledge Hub Website Training Says Sitemap Does not exist

I submitted a sitemap to my chat bot agent and it worked fine, but after removing and trying to add back I keep getting an error saying “Your sitemap does not exist”.
The sitemap does exist and is in the correct format (I use rank math seo to generate sitemaps for wordpress websites). Other website sitemaps can be added, but not the original one I initially added.

Hi jm2467

can you please send me via private message your sitemap url?
