Nuget package Aspose.Words-Cloud 23.5.0 is working fine with both the cloud version and the self-hosted Docker container.
Versions 23.6.0 and 23.7.0 throw ApiException “Forbidden” when calling the self-hosted Docker container, but work fine with the cloud version.
To reproduce, it is enough to run the C# code from https://docs.aspose.cloud/words/convert/word-to-pdf/ , for example.
