I have a QNAP TS-410U running an iSCSI target with 2 LUNs. I am not using CHAP authentication.
Since a reboot, everytime I try to connect to the iSCSI - either to a Virtual Disk on the device itself or from an external device, I am getting an "Authentication Failure".
Can anyone point me in the right direction? I have backed up the settings and attached the .bin file if that is any use.
