New consumer keys (and secrets) don't work with request_token


Hi. I’m having some basic auth problems with a newly created app.

I’m using Perl and Net::Twitter. Testing the simple example in

seems to work (using developer’s key). But if I use my new consumer key and secret, all I get is:
Net::Twitter::Role::OAuth::get_authorization_url(): GET failed: 401 Unauthorized at

Yes, “Sign in with Twitter” is set to Yes. I’ve tried to reset the keys. I’ve even tried other newish pairs.
Any ideas? Thanks,
