Default document not processed in CF2021/IIS 10/Windows Server 2019

[benjamink20141604]

I am experiencing a very strange behavior with respect to default document processing.

If I explicitly go to https://server/index.cfm, the page loads without issue.

If I go to https://server/  I am getting the following error:

I have enabled failed request tracing in IIS, but nothing is being logged there either.

I would then expect you to see errors or warnings in \config\wsconfig\{Magic Number}\isapi_redirect.log. Please share them with us.
