“Failed to validate oauth signature and token” on Twitter Oauth – Check Your Clock!

Thanks for this post. I was also banging my head on this problem and a `ntpdate pool.ntp.org` did wonders!

Thanks

doh!

Thanks Blaine, I too was banging my head against a wall with this. The sample code is pretty simple so it just didn’t make sense.

thanks!

ha, so glad this article exists. could have wasted so many more days. google, can we get some more juice?

[...] I went back to Google and searched for this error. One of the first results was, “Failed to validate oauth signature and token” on Twitter Oauth – Check Your Clock! My first thought, “Ah [...]

I spend 2 days going over and over through my code trying to figure out what could possibly be the issue with my code. I then submitted multiple support requests to Twitter with either no response, immediately closed tickets, and lots of frustration.
Upon an extensive search, I found this post and had my problem fixed in less than 3 minutes.
Thank you so very much for posting this information.

I ran into the same issue on various servers but with identical (rsync’d) code on other servers it worked fine.

The difference I noted was the PHP version in my case. Working servers were 5.3 and non-working servers were still 5.2. The difference between the two is that PHP 5.2 encodes the ‘~’ into ‘%7E’ but PHP 5.3 now considers it safe and leaves it as is.

My callback url had a ~ in it therefore generating the request with PHP 5.2 encoding it would result in a mismatch with twitter and would fail.

Hope this helps anyone that comes across this page like I did searching for answers and the date solution doesn’t help.

THANK YOU! Almost a year later and your blog post is still saving people from ripping their hair out!

thanks!

Thanks a lot!!!

Thank you really much for this hint!

Wowy-zowy! That sucks. What an obscure problem to figure out. Thanks a bunch to whoever did that crazy legwork.

Thank you!

(check your server clock if you run it in virtualbox and suspend the host computer)

Thank you very much for this precious post.

But what if the site is living in another timezone than US?

Italy, for instance.

Is one forced to set system time as US-centric?

Thanks again,

Freddie

Hello People, thanks for the sharing and it saved our team a lot of time ! thanks for sharing

Keep it up.

Hi
thanks a lot you saved my day

@Freddie. You know that is a good question. I don’t think that is the case however since there are multiple time zones here in the US. I don’t know the spec offhand, but that has to be somehow figured in when creating the token.

Thanks again…solved my issue.

Thanks dude! I have been struggling with this issue, finally came across your post.

Alrite, my clock is set to the default LAN time settings as I work in a WORKGROUP at my workplace.
My PHP settings have a default timezone specified and set to Asia/Calcutta.
Should I do anything specific, or different, to make my code work? ‘Coz I’m still gettin an error

thanks man . this helped me a lot!!!!!!

Thanks! You saved me 1.9 weeks of frustration

im sorry but i dont know much about pc or anything and i having this problem and i honestly dont know how to fix i try to change the hr but still not working help!

My app worked a couple weeks ago, now I went to do some more work on it, and it was failing.

Clock had drifted 20 minutes behind, and now all working again thanks to your post.

Hi, How do I fix this issue if it a desktop application and on different timezone?

‘siteUrl’ => ‘https://twitter.com/oauth/authorize‘

make sure that your URL is correct in the request.

HI,
can i get access token through ajax.
bcoz i am gettin error
Failed to validate oauth signature and token

Great Man, but why it is depend on time? example if i work on wrong time then i change valid time i will get this issue so how do i fix permanently ?

It shouldn’t have anything to do with Ajax. Get it working without ajax first and you should be fine.

I believe it depends on time because the token makes use of a nonce to make sure it is unique and used only once. I believe there is a little bit of flexibility to accommodate for being seconds off. However, I don’t think you can be hours off.
If your issue IS indeed the time, the permanent fix is to make sure your production machine always has the correct time for its timezone. Depending on your setup, you can use automated sync tools to manage this.

thanks a ton..two days wasted. I won’t have reached to this conclusion.

i had this new ubuntu machine setup without doing proper time adjustment. It was only 12 hours diff..but that was not making it work..

thanks !!!

On OSX 10.6.6 I just turned the Apple official time (it was on manual) and Kaboom! Everything works fine! Thank you!

Thanks for sharing this tip! It really made me mad! I spend half a day already.

Thanks so much!

OMG! I’m not actually a developer, but I downloaded the Twitter for Mac app and have been trying to log in, but it kept giving me the same error code! I gave up for a couple of weeks, but you saved my life! THANK YOU!

That worked. Saw your name while going through the oauth library written by Abraham. Then I arrived at this page and got the solution to my problem. You are a good omen Blaine!

Thanks for the info! I was having this issue, after copying a library that I knew was working on another server, and all that was different was the tokens.

That is just ridiculous! Why is twitter make it so difficult? The login with facebook is 1000 times easier. 
Which timezone should I select on my server? There are 3 timezones in the USA. In which timezones are the twitter server located? Any thought? 
THX.
