get_request_token fails with File not found error

I am having the exact same problem, i try to connect here:

https://api.login.yahoo.com/oauth/v2/get_token

and boom, file not found. What is weird is that if you replace v2 with V# (ie, v1, v9999, v23235) a page at least comes up. Its like something specifically broke at that url.

I don't see how we can do oauth authentication until this has been fixed.

UPDATE:
When inspecting the headers i get back a
"OAuth oauth_problem=signature_invalid" error. Not sure what to do about this yet

Update:

REQUEST:
https://api.login.yahoo.com/oauth/v2/get_re...lt;<CONSUMER KEY HERE>>&oauth_signature_method=plaintext&oauth_signature=<<CONSUMER SECRET HERE>>&oauth_version=1.0&xoauth_lang_pref=en-us&oauth_callback=http://sportsbuzz.local

finally got it, went back over the parameters with a fine tooth comb and finally got it to work. I wish Yahoo would make the error responses a little more user friendly.
