We've spent quite some time to locate the reason for the following exception:
The remote server returned an error: (403) Forbidden.

...The rest is removed for clearity...
As a last resort we changed the App-service environment setting from 32-bit (seems to be default) to 64-bit and the problem was solved. No more forbidden exceptions.
We still don't know why 32-bit should cause the exception. Does anybody know why? Would be nice to know.
Update
Assemblies in our solution are compiled as .NET 4.6.1/Any CPU
Some of the theories we have
- Nuget/Azure incompatibilities (versioning)
- JIT-compiler 32-bit/64-bit differences
- Timing issues with 32-bit (authentication and server-clock)
- Other...
