CentOS - Apr 2018 - iscsiadm: Could not perform SendTargets discovery: encountered non-retryable iSCSI login failure

Hello

I know this not the place to ask help, but i can't send messages to iscsi
list. :(


I have 3 CentOS 6 connecting to a ISCSI server with Targecli suddenly they
lost connection and i receive this error when i performance iscsiadm --mode
discovery --type sendtargets --portal x.x.x.x

iscsiadm: Could not perform SendTargets discovery: encountered
non-retryable iSCSI login failure


I have already changed the password for the ACLs.

Thanks for attention.
