S3導入したがExcon::Error::Forbidden (Expected(200) <=> Actual(403 Forbidden)

Question

内容

S3を導入したのですが、画像を投稿した際に「 Excon::Error::Forbidden (Expected(200) <=> Actual(403 Forbidden)」という内容のエラーが出てしまいます。
アクセスキー、シークレットキーが異なる場合に出てしまうようなのですが、アクセスキー、シークレットキーは新たに作成してコピペしたものでした。
内容が間違っているように思えず、他の原因が考えられたら教えていただきたいです。

●試したこと
config/initializers/carrierwave.rbのアクセスキー、シークレットキーの内容が間違っている可能性を考え見返しましましたが、正しく記入できていました。

エラー内容(production.log)
