I have a next-cloud server i want to access from a Windows 10 installation as a network drive. I can acess the web interface, but as soon as i try to add the network drive via the explorer- i get a error: The group policy does not allow connections without a missing smartcard.
Smartcards are not permitted and used in our network.
Solution was to check the self-signed certificate on the next cloud instance. Turned out there was a exepction active in the web interface, but the certificate was not integrated into the windows trusted root keystore. Once the certificate was added via mmc.exe, the error vannished, replaced by a request for username and password.
