AD Join Error after Reboot

I have a system, it was on 11.2 u7 and did an upgrade to 11.3 u2

All went fine except the Directory Join.

It has a strange bug, if I restart the system, it says in the AD Status FAILED, but if i issue a wbinfo -t, i have no error, and it says RPC calls succededed, but in the GUI the status is failed.

If in GUI I uncheck enabel and r-check it, the GUI status changes back ti green 

Any help?
