Failed to validate oauth signature and token

[computerzworld]

Hello,
I am using Twitter Oauth library for signing in to Twitter
& getting access token for posting tweets programatically. But when I
am trying to run the application on my server it is giving me error
like

"Failed to validate oauth signature and token"

I tried to move the application on another server & it is working. So
what should be the problem behind this? Is there any configuration
required for the server in order to make this work? Please help me.


Thanks in advance.

Your servers clock needs to be properly synced using NTP.

Thanks for your reply. Is there anyway to sync server clock
programatically? Or any other way by which we can make the stuff
working? Because I don't have access to server hardware.

The server administrators can and should sync server clocks
automatically to the world time clocks using Network Time Protocol
(NTP). If your "IT department" isn't doing this, find out why not.
Most likely they don't know it's possible. It's pretty easy on Linux
and Windows, but you do need an Internet connection to the outside
world, so the firewall folks need to be involved and you have to make
sure your server-side NTP software is kept up to date on security
patches.

In addition, the server time is returned in the HEAD of every response from the Twitter API. If the first request fails you can inspect the time returned in the HEAD and calculate the difference between it and your local time. You can then add/subtract that difference to the timestamp you use for OAuth requests.

Hope that helps,

@ Matt Harris
I checked the header from twitter & my server's
header & I found difference of 1 hour & I have set the time using
date_default_timezone_set to GMT using PHP. But still its giving the
same error. What should be the problem behind it? Thanks.

Problem solved! I have synchronized my server time to NTM using WHM &
it worked! Thanks all for your help.

I am facing the problem again even after server time sync. Getting the
same error again. Now what should be the issue? I am getting stuck
again :(
