Ok,
Everything is Ok now!
From ERAS log:
<SESSION_ERROR> CCServiceRoutine(InsertClient): MAXIMUM NUMBER OF CLIENTS REACHED, 'XXXYYYXXX' NOT ADDED. Please upgrade your license (connection 'XXX.XXX.XXX.XXX:9658', 34 in db, 34 in license)
I don't know why my server tried to add itself as a new client... just deleted my server old entry and now it's ok.
Thank you.
