Checking out if something has changed in the meantime with the RSS feeds of the blogs on dotnetnuke.com, I saw that something has changed. The RSS icons for the Sub-blogs are gone now and there is a new rss icon above that aggregates all rss feeds.
Checking this out I saw that it works fine in the browser - so I started to debug my bbnews module (rss feed aggregator module on codeplex) why this throws an error when reading this feed.
I tried a few methods to read this url in c#, e.g. this simple one:
string url = "http://www.dotnetnuke.com/Resources/Blogs/rssid/0.aspx/";
var rssXml = new XmlDocument();
rssXml.Load(url);
Every method throws the same error: From the transport connection can not be read: The connection was closed. (Free translation from german)
Fiddler shows more details on this error, perhaps this helps:
This is NOT an issue of the blog module generally (I use it on my website also), It is specifically an issue on dotnetnuke.com !
