With Domino 9 server, a new Virtual Hostname doc has been added to the Domino Directory for domain xxxxx.app. It is configured with default values, and there are several other web sites hosted on the server with the same configuration. SSL is running on one of the domains, but all the rest are HTTP.
However, the site is not accessible via the browser giving the error message:
403 FORBIDDEN (Access not allowed even with authorization)
The only difference between this site and the others is that it has an .app high level domain name, and it was added to the Directory after the SSL key had been installed for a different domain name.
What may be causing forbidden access even with authorization?
