Can't able to get access tokens in Mangeto 1.9 - magento

Question

I am trying to get the permanent access_token and access_token_secret from Mangento 1.9.
I have consumer_key and consumer_secret and have configured the required permission by following this link http://devdocs.magento.com/guides/m1x/api/rest/permission_settings/permission_settings.html
I have successfully generated the temporary access_token and access_token_secret. But while trying to generate the oauth_verifier I am getting:
An error occurred. Your authorization request is invalid.
How can I solve this problem?

You can generate permanent access token and and token secrete using Postman.
Follow the link.
