Twitter module Oauth 'TwitterException' with message 'Unauthorized' When trying to authenticate a Twitter account using the Twitter and OAuth modules, I get the following error


  Could not obtain a valid token from the Twitter API. Please review the configuration.


I have since found that The following error is recorded in Watchdog


  exception 'TwitterException' with message 'Unauthorized' in /var/www/html/sitex/public/sites/all/modules/twitter/twitter.lib.php:151 Stack trace: #0 /var/www/html/sitex/public/sites/all/modules/twitter/twitter.lib.php(114): Twitter->request('https://api.twi...') #1 /var/www/html/sitex/public/sites/all/modules/twitter/twitter.lib.php(51): Twitter->auth_request('https://api.twi...', Array) #2 /var/www/html/sitex/public/sites/all/modules/twitter/twitter.pages.inc(343): Twitter->get_request_token()
  
  [Abridged]


Having checked out the URL which is generated and sent off by drupal_http_request I get the following error message


  Failed to validate oauth signature and token


I have checked the following


Followed https://drupal.org/node/1346824
Reinstalled both the Twitter and OAuth modules
Ensured my OAuth Consumer key is correct
Ensured my OAuth Consumer secret is correct
Ensured I have Read &amp; Write permissions
Ensured my server time is within 5 minutes of Twitter's as per this thread
Ensured my server is running extension=php_openssl.dll
Ensured my callback URL is correct - http://mywebsite.com/twitter/oauth

Note that I am not on localhost, nor is my host behind .htaccess


Visiting my callback URL results in the following error at /admin/config/services/twitter


  The connection to Twitter failed. Please try again.



I am not on localhost, but have tried the suggested 127.0.0.1 callback URL regardless.
I do a version compatible/containing "Patch 5" as mentioned here
I'm using the following versions of the modules


Twitter 7.x-6.0-alpha2+1-dev (But have tried 7.x-5.8 too)
OAuth 7.x-3.1
Core 7.22



I haven't enabled the following- Do I need to?


OAuth Provider UI
Twitter actions
Twitter Post
Twitter Signin


I'd appreciate it if anyoneis able to provide insight!

Thanks
This just started working with no change- I can only assume it was a temporary problem with Twitter at the time.

To some degree a useless answer, but the question gives others a list of things to try in the same situation and allows me to mark this question as resolved.
