anonymous user You need to use https://fs.zero365.net/adfs/ls/idpinitiatedsignon to go to ADFS Authentication page.
Note: On Windows Server 2016 and later, this page is disabled by default and needs to be enabled by using following command:
Set-AdfsProperties –EnableIdpInitiatedSignonPage $True
If you want to redirect to http://zero365.net after authentication, your web application must be federated with ADFS and configured to redirect to http://zero365.net after successful authentication. for more information, please search for "ADFS Deep Dive" on https://techcommunity.microsoft.com.
Also, you should not name any of the actual computer accounts in the ADFS farm fs.zero365.net, which will cause a duplicate SPN issue and break integrated Windows Authentication.
