Problem with the KNIME RSS feed reader node?

Hi, I recently started using the RSS feed reader node from KNIME and realized that many RSS feeds are not read at all and I don’t see why. For example this one in the supported RSS 2.0 https://www.rki.de/SiteGlobals/Functions/RSSFeed/RSSGenerator_nCoV.xml

Maybe there is an easy solution to that. I don’t want to use Palladian or extract all data manually with xpath.

Many thanks in advance
