I'm having the same problems. The solution posted above doesn't seem to apply to the issue for the majority of the people in this post (the solution was for a custom module ).

So try this on for size. Take a clean DNN portal. Add the blog module and create a blog posting (with syndication enabled). Click on the "XML" button and copy the url to that feed.

Now add a News Feed module to the page and use the XML feed to the blog as the source of the news feed. Click update. You'll see the error immediately.

Now, go back and change it to an external XML feed from another site and it will work perfectly. I've gone over and over this to make sure this wasn't something goofy on my end (like hiding the xml feed via module permissions).

This error has been present (that I know of) on DNN 4.xx (I'm working on a 4.3.4 install now trying to make this happen). In my case the error can be duplicated on the live production box and my clean localhost install.

I use this same technique on my company website blog (www.dallasnewmedia.com - right colum "recent articles") and it works perfectly. It's a DNN 3.0.3 install.

ok it looks like this problem occurs when you have ad intergrated into the DNN.

to test comment out the following line in the web.config file:

<!-- <add name="Authentication" type="DotNetNuke.HttpModules.AuthenticationModule, DotNetNuke.HttpModules.Authentication" /> -->

It will magically work!

Now i thought maybe you could pass the credentails through to read the news feed but being a beginner like me im not sure if i have got it right or if this solution will work around the issue??

I have tested the code below and it works just the same if i dont use the credentails, ie works without ad authentication but not with.

code as follows:

<script language="VB" runat="server">

Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

recentPosts.DataSource = GetRSSFeed(http://webserver1/DotNetNuke/DesktopModules/Orizonti_NukeNews/getRSS.aspx?pid=0&tid=36&mid=465&cnt=5)

End Sub

Function GetRSSFeed(ByVal strURL As String) As DataTable

'Get the XML data

Dim resolver As XmlUrlResolver = New XmlUrlResolver()

Dim myCred As New Net.NetworkCredential

myCred = New System.Net.NetworkCredential("username", "password", "domain")

myRequest.PreAuthenticate = True

Dim myResponse As Net.HttpWebResponse = myRequest.GetResponse()

Dim responseStream As IO.Stream = myResponse.GetResponseStream()

'Dim reader As New XmlTextReader(strURL)

Dim reader As XmlTextReader = New XmlTextReader(responseStream)

'reader.XmlResolver = resolver

'return a new DataSet

Dim ds As DataSet = New DataSet()

Return ds.Tables(2)

End Function

</script>

Hi, I had the same issue some time ago, and in my case it was a firewall problem. I had no access to local HTTP port 80 and localhost.  After granting access everything worked fine.

If you wish to create a feed from your own website and post it on the same website you have to add in firewall a rule to allow your web server to access its own resources.

Hope this helps you in the future.
