Facebook C# SDK : No connection could be made because the target machine actively refused it

I've downloaded the latest version of the C# SDK - using Windows 7, VS 2010 and .NET 4.

I've got the website running on my local IIS 7.

I have a Facebook developer account etc. and am trying to get the CSASPNETFacebookApp sample working.

When I access my app. I get the Facebook logon and border.

I logon and then get:

No connection could be made because the target machine actively refused it 66.220.146.50:4开发者_如何学Go43

nslookup 66.220.147.38

shows

Name: api-read-12-04-snc4.facebook.com

Address: 66.220.147.38

Any ideas?

Have you set the URL's correctly in the application settings page on Facebook? Is the "Site URL" set to http://localhost:xxxx for example?

I get this all the time from the Graph API. I think it's Facebook's fault. I think because they have too many connections it sometimes won't query your data and give you results back. In my experience, I do all my Graph requests in a loop that repeats (max of 4 times) when that error occurs. ususally the second or third time it works. Some times it just doesn't. IDK

Try the loop and see if that works
