zend framework - Twitter authentification Failed to validate oauth signature and token -

i created twitter authentication on website , worked fine, after time started receiving error message "failed validate oauth signature , token". have changed consumerkey , consumersecret, didnt help. use zend framework. here first step:

public function authtwitteraction() { $zendconfig = zend_registry::get( 'zend_config' ); // instance oauth consumer config options $consumer = new zend_oauth_consumer($zendconfig->twitter->toarray());                      // using default session namespace, store request token serialized $session = new zend_session_namespace(); $session->requesttoken = serialize( $consumer->getrequesttoken() ); // redirect user twitter.com $consumer->redirect();  } 

i send consumerkey , consumersecret http://twitter.com/oauth , it's callbackurl: http://onlinefitnesclub.ru/twitter. changed in twitter?

i have solved issue. send request http://twitter.com/oauth, when changed protocol https://twitter.com/oauth work fine again.
