debian to iscsi connection error: 19 - encountered non-retryable iSCSI login failure

Question

User identification

Good afternoon. When trying to establish a connection from debian 6 to iscsi target on NAS
, the following error occurs
: iscsiadm -m node -T target-1 -p *.*.*.* -l
Logging in to [iface: default, target: target-1, portal: *.*.*.*,3260]
iscsiadm: Could not login to [iface: default, target: target-1, portal: *.*.*.*,3260]:
iscsiadm: initiator reported error (19 - encountered non-retryable iSCSI login failure)
Specified both in the config and manually
iscsiadm -m node -T target-1 -p *.*.*.* --op update -n node.startup -v automatic
iscsiadm -m node -- targetname "target-1" --portal "*.*.*.*:3260" --op=update --name node.session.auth.authmethod --value=CHAP
iscsiadm -m node --targetname "target-1" --portal "*.*.*.*:3260" --op=update --name node.session.auth.username --value=login_name
iscsiadm -m node --targetname "target-1" --portal "*.*.*.*:3260" --op=update --name node.session.auth.password --value=pass
Where else can you dig?
