We have an EP 11.9.0 website  on an Azure VM  https://www.clienthost.com with the editor accessible via https://editor.clienthost.com.

The domains are behind Front Door.

In past times the editor hostname used to be https://admin.clienthost.com and that host is still in the host definitions .

When someone fills in an Episerver form on the website and the email notification goes through to the website manager, the link for the uploaded file uses the old admin.clienthost.com host in the link which is no longer valid. The form uses the built in Episerver functionality with no customisations, controllers or what not.

One thing is that the form is on a /de language page, and our primary host is not set up with cultures.

The system is only on 1 server. It used to be on 2, an admin server and a public facing server.

Does anyone know why Episerver is creating the link with this outdated host rather than the primary host www.clienthost.com ?
