Azure App Service - Custom Domain and SSL Binding

Question

Hello,

We have an Azure Web App Service, where we create custom domains. I was recently given access to the "Contributor" role for this web app. I am able to create and verify custom domains successfully. However, the SSL binding is failing due to an error stating that I am not authorized to do this.

I have tried the following steps, but found no luck:

1. Refreshed my credentials by logging out and log in back in, tried it in a different browser
2. Checked with the Azure Admin and confirmed I have the Contributor role access
3. The Contributor role does have the Certificate Write permission
   
4. I am using the below setting while binding the SSL.
   

Any help related to this issue would be greatly appreciated. Thanks in advance.
