401 error, Timestamp out of bounds

sufengster · 2011-07-28T10:44:49.000Z

I developed a client app using twitter4j, it running well for several months.
But today, I got the following error, what is the reason? I have run ntpdatetime.nist.gov on the server.

401:Authentication credentials ( http://dev.twitter.com/pages/auth) were missing or incorrect. Ensure that you have set valid conumer key cret, access token cret, and the system clock in in sync.

RazaJunaid · 2011-08-17T04:59:00.000Z

I do have the same problam I have checked every thing the consumerkey/consumerSecret ,
AccessToken /AccessTokenSecret all are according the web page mention but posting tweet gives this exception.

This error cause time on your server is not equal with time on twitter server, please re-config your time.

mtarroyo · 2011-08-23T17:50:39.000Z

Thanks a lot! I just changed the server’s date and everything worked just fine.

freddurao · 2011-09-26T13:33:27.000Z

Hello,

man how do you manage to change the server’s date?

episod · 2011-09-26T14:17:11.000Z

It depends on the server environment you are in.

An alternative to setting the system clock is to occasionally send a HTTP HEAD request to Twitter’s help/test end point. Within the response will be a HTTP Date header indicating Twitter’s server time. If you compare that time to the current time on your machine and then regularly adjust your oauth_timestamp values by the difference, you can stay synced to Twitter’s time without adjusting your clock.

chidambarambest · 2011-10-20T12:18:21.000Z

I am using windows 7, the date time format is UTC where as twitter return the datetime as GMT.
updated the date time even as in twitter server even then I am getting the same issue( oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Server returned HTTP response code: 401 for URL: http://twitter.com/oauth/request_token).Can any one please suggest me to fix this issue.

thanks u so much

soodgniit · 2012-02-07T11:40:48.000Z

Hello Sir,

I think oauth signature is based upon server time, but to change it as we are on shared hosting and if we change the time of server it will affect other projects, please let us know the solution

waiting for reply.

episod · 2012-02-07T15:45:29.000Z

Think about the problem a little differently – it’s not that you necessarily need to set the clock to a different time, you just need to account for its drift in all your time calculations. When you issue a request to the API (perhaps consider using a HEAD request https://api.twitter.com/1/help/test.json ) you’ll get back a “Date” HTTP header like:


Date: Tue, 07 Feb 2012 15:43:53 GMT

Convert that timestamp to epoch time and compare to your system current epoch time. The difference in seconds between the two is right about where you want to adjust your current timestamps to.

I’d do this process no more than once or twice a day to keep in sync.

Hi, I can know how you solved your problem with the error: “timestamp out of bounds”

therealquaki · 2012-05-10T21:18:00.000Z

Hey,
can you tell me, where and how I have to adjust my timestamps?
So, I found out that my system time is 2 hours (7200 seconds) later than Twitter’s server time.
Then, in OAuth.php I changed the function:
private static function generate_timestamp() {
return time()-7200;
}

But there is still a 401 error. I did a print_r($twitteroauth):

And my system timestamp was: 1336684598

Do you have an idea what to do now?

kurrik · 2012-05-11T22:14:11.000Z

Are you purposely obscuring your consumer key and secret in that request, or are those values actually being sent as YOUR_CONSUMER_SECRET ?

jama21ve · 2012-06-03T02:13:26.000Z

Sorry, i am new in this. Exactly how can i adjust the oauth_timestamp values?.. The code goes like this:


   $defaults = array("oauth_version" => OAuthRequest::$version,
                      "oauth_nonce" => OAuthRequest::generate_nonce(),
                      "oauth_timestamp" => OAuthRequest::generate_timestamp(),
                      "oauth_consumer_key" => $consumer->key);
private static function generate_timestamp() {

return time();

}

Im unable to change the server time because its not mine. I would appreciate any help you could give me…

Check if you have special chars like íñó

RListnet · 2012-09-13T16:46:43.000Z

If your problem is with tildes replace with the equivalent with entities numbers from here http://www.texaswebdevelopers.com/examples/xmlentities/xml_entities.asp
