If this happens try to set useCorsProxy to false in your feed config. Like this:
modules: [
{
module: "newsfeed",
position: "top_right",
config: {
feeds: [
{
title: "tagesschau.de",
url: "https://www.tagesschau.de/xml/rss2/",
useCorsProxy: false
}
]
}
},
{
module: "MMM-News-QR",
position: "top_right",
config: {
updateType: "push",
interval: 2000,
animationSpeed: 2500,
colorDark: "#fff",
colorLight: "#000",
imageSize: 150
}
}
]
