How-to: Password-less FIDO2 Security Key Sign-in to Windows 10 HAADJ Devices

MiguelRodriguezS, G-At-Work, jmcz1: Yep, can confirm the issues. Currently most of our customers are working from home, so (without VPN) there is no access to the Domaincontrollers. When the login is performed the error Dominik_Gruber mentioned appears. Event log reports no connection to DCs. After the user performs a login with line-of-site connection logins will go through without errors even without line-of-site connection afterwards for, what it seems like, 2 days until the error/issue reoccurres. Seems like that even with VPN connection set to active there is still a problem with the connection to the DC in our case. Is there any documentation about Ports and URLs needed or any update about if the feature will support successful logins without line-of-site connection LijuV?
