Why this?

Am I guessing correctly that this: Zammad create folder is a duplicate of this topic?

Zammads default webserver configuration files to not provide options to have custom folders and thus all requests are routet to Zammad as application. As /dh is no valid endpoint in Zammad, you’ll receive above error message.

If your configuration says it should allow the access, your webserver may fall back to the Zammad configuration. Not sure if we can help with that exactly.

Your webservers log files may provide information which vhost was re acting. You could start from that part.
