Freenas 11.3 upgrade to Truenas 12 beta iSCSI connection drops

[cougarmaster]

I have upgraded to Truenas 12 beta without upgrading the pool and everything works no problem except iSCSI just would not connect then I reinstalled Freenas 11.3 samething just would not reconnect. Then used Truenas 12 beta again and upgraded the pool and still will not connect. Now cannot goback to 11.3 because the pool was upgraded and no way for me to connect to iSCSI even if I create a new zvol it will just keep reset by peer and then drops and hangs the nic. I even did a clean install and tried also same so something corrupted the pool? But everything is normal just only iSCSI. Also removed chap.
