"Login to Facebook" returns to the same page

Hey,

I've set the permissions correctly, but still nothing seems to happen.

Unfortunately, that doesn't seem to fix the issue.

It all works fine on my local server, but it doesn't on the live one. It's likely something server related, but I have no idea what could be causing this..

Do you mean on Facebook? Yes, I did.

What field do you mean exactly?

But on my local server I can get it to work, it's just when using the live server this issue appears..

I've entered it in this format:

http://www.website.com/

I've also tried different formats already, but without luck.

I've debugged the whole code and believe I have found the cause of this issue. You might also want to check this out sumithra ramalingam, if none of the other solutions on the internet seem to work.

In the SDK (base_facebook.php), there's a function getAccessTokenFromCode with this code:

    try {
      // need to circumvent json_decode by calling _oauthRequest
      // directly, since response isn't JSON format.
      $access_token_response =
        $this->_oauthRequest(
          $this->getUrl('graph', '/oauth/access_token'),
          $params = array('client_id' => $this->getAppId(),
                          'client_secret' => $this->getAppSecret(),
                          'redirect_uri' => $redirect_uri,
                          'code' => $code));
    } catch (FacebookApiException $e) {
      // most likely that user very recently revoked authorization.
      // In any event, we don't have an access token, so say so.
      return false;
    }

Here it seems to go wrong. An exception occured, but isn't handled at all. Printing the error, I get:
Failed to connect to 2a03:2880:20:4f06:face:b00c:0:1: Network is unreachable

Adding CURLOPT_IPRESOLVE => CURL_IPRESOLVE_V4 in $CURL_OPTS should normally force it to use ipv4, however, in my case an exception still occurs telling me there's a timeout.

I think something is misconfigured or blocked on the server side. I don't manage the server, so I have to wait until the server guys can have a look at it.

After some adjustments on the servers, it now works fine! My issue was indeed related to the ipv6 configuration on the server and the firewall blocking certain CURL requests.

I also had the problem of not getting the access token. This was because of the above issue.

sumithra ramalingam, to confirm that you have the same issue as me, find the code I posted above and add these lines above "return false;":

var_dump($e);
die;

If you try to login to Facebook now and you have the same issue as me, you should get a white page with debugging information. Don't forget to remove the lines again afterwards.

In that case, you have a different problem. When I was looking for solutions, I found a lot of different causes for this...
