Generated feeds cannot be read by any RSS readers

[stoltenhoff]

After successful installation of 2023.03.22~ynh1 i'm not able to use the generated feeds in other feed readers. Then i generated exactly the same feed via a public RSS Bridge instance which led to the exactly same url (after the core-ip itself, of course). The url from the public bridge is working while the url from my server is not? There is no specific error message beside that the feed cannot be found. (For example NetNewsWire said »Can’t add a feed because no feed was found«)
