I'm trying to connect a Windows System (current Win10 or Server2019 LTS) to a Linux tgt iSCSI-target. The target-server works fine with Linux initiators, but with a Windows initiator I always get an error in the GUI saying "The target name is not found or is marked as hidden from login".
I tried no authentication, initiator-authentication, CHAP and mutual CHAP, to no avail...
Any ideas what's wrong here?

    Problem solved: Ubuntu does not conform to RFC 3722 "String Profile for iSCSI Names" which states "In addition, any upper-case characters input via a user interface MUST be mapped to their lower-case equivalents."
    My host is named UV1, so I set up an IQN like "iqn....:UV1-test" but the Windows initiator connects to "iqn....:uvi1-test" which is met with a "Target not found" ...

    Hi，

    Please try to configure the Local adapter, Initiator IP and Target portal IP of the ISCSI target, then try to connect again, check if it could work:

    Click the ISCSI target in the list, click connect, then click advanced, configure the settings:

    Thank you for the fast reply! I tried that, as well as combinations of header / data digest, but still the same error. I also had a look at the event log and I get the following error: "Source iSCSIPrt / ID 10 / Login request failed".
    It's really strange, my Windows initiators connect happily to Windows, FreeNAS and AsusTor targets. My only issue is with Windows initiators and Ubuntu / tgt as the target??
