Streaming API 503 Server Unavailable

Oct 7, 2011 at 2:25 PM

Hello I'm new to working with twitter but I keep getting the above error.  The twitter API status page shows the Streaming api to be all green so I assume that I've made an error.  Below is my code and auth is already authenticated.

ctxStream = New TwitterContext(auth, "", "")

Dim count As Integer = 0 Dim s = (From strm In ctxStream.Streaming Where strm.Type = StreamingType.Filter AndAlso strm.Track = "foxnews" Select strm).StreamingCallback(Sub(strm)


                                                                                                                                                                                                                                count += 1

                                                                                                                                                                                                                                If count >= 2 Then


                                                                                                                                                                                                                                 End If

                                                                                                                                                                                                                              End Sub).SingleOrDefault()

There are a couple things to look at, Twitter base URL and credentials.  You should instantiate TwitterContext with the Twitter base url set like this:

ctxStream = New TwitterContext("", "")

and then set UserName and Password like this:

ctxStream.StreamingUserName = "<your user name goes here>";
ctxStream.StreamingPassword = "<your password goes here>";

I'll make a note to update the VB examples and please let me know if this doesn't work.

Thanks for the quick response

I don't know if this was a typo or what but there isn't a constructor for twittercontext with just the urls, but i tried just editing the urls in my current code and adding the user name and password, but the same error popped up.

Okay, thanks for letting me know.  I'll try to reproduce.  Don't have time right now, but will try to take a look this weekend.  In the meantime, you might want to hook up Fiddler and take a closer look at what Twitter is sending back to you - sometimes this is very revealing and sometimes I can't reproduce the same thing.

Actually I may have found the issue but I'm not sure how to solve it.  It seems to be sending the request to, but when I redirected it to with fiddler it gave me an unauthorized error

I don't know what happened but it seems to be working fine now.  Thanks for the help though
