【Rails】現在作成中のWebアプリケーションにTwitterを利用したSNSログイン認証ができません

前提

現在RailsでWebアプリケーションを作成しております。
以下、2つのgemを利用しアプリケーションでは、
すでにGoogleアカウントを利用したSNSログイン昨日は実装できております。
'omniauth'、'omniauth-google-oauth2'

実現したいこと

Twitterのアカウントを利用しWebアプリケーションにログインするSNS機能実装したいです。
また、ローカルで実行できていたので、本番環境にデプロイし、
アプリケーションの画面上からtwitterでログインを実施したところ、「Internal Server Error」と表示されてしました。
Unicoenのエラーメッセージは以下のようになっておりました。

試したこと

エラーメッセージの内容の（OAuth::Unauthorized (403 Forbidden):）について調査したところ、
同様の事象が起きていることがあったので参考に
Twitter DeveloperのコールバックURLを見直しました。
こちらは初めから設定していたのでこちらでは解決に至りませんでした。

前提条件でも記載がありますが、ローカルでは正常に動いているので、
Unicorn、nginxの設定の問題だと思っております。
こちら設定をどのように変更すれば正常に動作するかお教え願えますでしょうか。
