When performing offline authorization and uploading the authorize.txt file to My Esri, the following error occurs:
Error: 6023; Input parameter hostId of TrustedHostEntityBO.createTrustedHostEntityBO cannot be null [Incident#]
If the hard disk of the machine is encrypted and has software client security installed, it prohibits the read or write of Unique Machine Numbers (UMN) in the authorize.txt file required for authorization.
Decrypt the hard disk and disable the software client security before creating the authorize.txt file.
Note: Consult the IT department for assistance.
