External RSS not working with sharepoint web part

Our application expose certain rss as http://myservername/feeeds/feedid=110. This link 开发者_StackOverflowworks with with all browser and i am able to see rss.

But when i provide same URL to our sharepoint web part, it gives me error and not able to get headlines.

I would double check the security of the feed. If it requires any sort of authentication (windows, forms, etc.), it will fail in the normal SharePoint web part.

If your application is on the SharePoint server then you're probably running into the Loopback check, which prevents http access from the server to itself using an other name than the real servername.

If this is the case then you can see how to disable the loopback check in this kb
