Our service is using Instagram Basic Display API Oauth authorizaion flow to exchange access token. https://developers.facebook.com/docs/instagram-basic-display-api/reference/oauth-authorize

But one of our company's client got the error while authorizing on instagram site, and was redirected to error page of instagram. https://www.instagram.com/oauth/authorize/third_party/error/? message=%E5%94%89%E5%91%80%EF%BC%8C%E5%A5%BD%E5%83%8F%E6%9C%89%E6%9D%B1%E8%A5%BF%E5%87%BA%E9%8C%AF%E4%BA%86%3A%20%E8%AB%8B%E5%98%97%E8%A9%A6%E9%97%9C%E9%96%89%E4%B8%A6%E9%87%8D%E6%96%B0%E9%96%8B%E5%95%9F%E4%BD%A0%E7%9A%84%E7%80%8F%E8%A6%BD%E5%99%A8%E8%A6%96%E7%AA%97%E3%80%82

I have no idea to resolve this situation, did anyone face the same situation?
