This app is misconfigured. Contact the vendor for assistance

[Faizan_Sattar]

I'm trying to install the bitbucket app on my site. I go through this article 'https://developer.atlassian.com/cloud/bitbucket/install-an-app-from-your-site/'
but I find an error " This app is misconfigured. Contact the vendor for assistance" 

My URL is: 'https://bitbucket.org/site/addons/authorize?descriptor_uri=http://local.symfony4-new.com/login/callback&redirect_uri=http://local.symfony4-new.com/gitregister/"

Someone, please help me I don't know what to do anymore.
