RSS-Feed for Blog is broken

Hello, the RSS feed in Nextcloud -> Blog does not work currently. The feed is generally not stable. For example in browsers it is not recognized as a RSS feed and the browser proposes asks for an application to open it, or says it can be saved as file. I use Thunderbirds RSS-reader and every other day I have to force Thunderbird to try to download news because it stopped to do it automatically. Since today it does not work anymore. In the error console the following message can be seen:

XML-Verarbeitungsfehler: Kein Wurzel-Element gefunden

Or does anybody know another way to get news about Nextcloud on a regularly basis?
Greetings

Try with this URL: https://nextcloud.com/blog/static-feed/

Explanation: the URL that appears on the blog page is finally redirected TWICE!!! You can realize of that if you run this command on shell:

wget https://nextcloud.com/blogfeed

The rare thing (unexplained for me) is that if you try to visit https://nextcloud.com/blog/static-feed/ on the web browser, then it is not loaded and the browser leave EMPTY !?

But i used the link https://nextcloud.com/blog/static-feed/ to successfully subscribe to Nextcloud News on my instance of NC app News… so, it runs. By now.

There is a server misconfiguration. The location /blog/static-feed is redirected to /blog/static-feed/ and vice-versa, so it is an infinite loop.
