RequestToken Oauth-plugin 401 Unauthorized

Question

I successfully implemented OAuth using the oauth-plugin gem with Rails 3.0.9. However, once I upgraded to Rails 3.1.3, I'm receiving an error when attempting to get the request token.

I've been testing locally

Rails 3.1.3 oauth (0.4.5) oauth-plugin (0.4.0.rc2)

I've setup the Rails app as a provider

Consumer Key: BkdI1PnzRuvKDw2Qs1wVxtDrtvmqhUgeXLwNpNtm Consumer

Secret: eCY7JFk4vK6IeWXVq7yS3OMVT1XKpVOWOImsy3iw

Request Token URL: http://localhost:3000/oauth/request_token

In the console:

ruby-1.9.2-p290 :003 > @consumer = OAuth::Consumer.new 
                                   "BkdI1PnzRuvKDw2Qs1wVxtDrtvmqhUgeXLwNpNtm",
                                   "eCY7JFk4vK6IeWXVq7yS3OMVT1XKpVOWOImsy3iw", 
                                   {:site => "http://localhost:3000"}

             :proxy=>nil, 
             :scheme=>:header, 
             :http_method=>:post, 
             :oauth_version=>"1.0", 
             :site=>"http://localhost:3000"}>

That means invalid OAuth request,can you verify that everything is correct like the secret/api key and client token — Umesh Awasthi, Dec 27 '11 at 01:11
Do check the the reasons for a 401 http://oauth.net/core/1.0a/#http_codes — Jesvin Jose, Dec 27 '11 at 10:08
I've double-checked the key and secret and tried it on multiple accounts. I have this implemented on the Rails 3.0.9 version of the same app, and it works as expected. I read that if the server time is off that it could cause the 401 error. The error message doesn't give the reason for the 401 error though. — strukturedkaos, Dec 27 '11 at 18:08
The only thing I can think of is that something changed between Rails 3.0.9 and 3.1 that is causing this error. — strukturedkaos, Dec 27 '11 at 18:32

I had this issue when my Virtual Machine's clock was behind. I just corrected the clock to match the current time and it worked fine after that.

Other causes are wrong application secret/key
