Authenticate errors

[BuzzTing]

I started getting errors yesterday with https://api.twitter.com/oauth/authenticate. At first it just returned a ‘Failed to validate oauth signature and token’ when requesting the session and then an hour later the error page appears. “Something is technically wrong. Thanks for noticing—we’re going to fix it up and have things back to normal soon.” This is still happening today. I cant see any status on this problem

Can you walk us through what your code is doing and exactly the error message and response code so we can try to reproduce?

I have been using TwitterOAuth php for months to get an oauth_token for https://api.twitter.com/oauth/authenticate?oauth_token=…

$conn = new TwitterOAuth($consumer_key, $consumer_secret);
$request_token = $conn->getRequestToken($redirectUrl);

Since yesterday the $request_token is ‘Failed to validate oauth signature and token’. My tokens and code are correct and had not changed for a long time

Thanks

After a lot of effort I discovered that simply revoking the app permission and starting again cured the problem. Something went screwey with the app permissions
