Hello @MathiasSchbel-5194, Welcome to the Microsoft Q&A platform.
As I understand from the question you are trying to configure HTTPS on your custom domain for Microsoft Azure CDN. You are enabling HTTPS using your own certificate which is present on your Azure key vault. You got error
'Exception of type 'Microsoft.Azure.Cdn.Common.ProviderPluginContracts.ProviderException' was thrown.'
I went through some issues internally with similar exceptions and there were usually two reasons for this exception.
- The TLS certificate created is not a complete certificate chain with leaf and intermediate certificates.
- The root CA is not a part of the Microsoft Trusted CA List.
These requirements are documented here.
Hope this helps! Please let me know if you have any additional questions. Thank you!
