AzurePack - 404 after Password Reset

Hi, 

we have Windows AzurePack installed (authentification WITHOUT ADFS). Recently we enabled the "forgot password" option.

now, when a user resets his password (works fine) and he want to log in with his new password, he receives a 404 error.

Changing the port in the addressbar of Internet Explorer from 30071 to 30081, the user is automatically logged in.

Is there a way to prohibit getting this 404? Maybe configuring the address the user will be forwarded to after changing the password?
