I have a FG 800C that was working fine

I Backup my configuration, edit it and restore it

now I cannot login to the unit,

every try resolve i wrong user and password

I Try to Login using Fortiexplorer with user "maintainer" to recover my password.

I can login, but when trying to reset password i get this massage:

FG800C # config system admin

FG800C (admin) # edit admin 'maintainer' account can only edit existing admins. node_check_object fail! for name admin

value parse error before 'admin' Command fail. Return code -37

It seems like there is no user name "admin"

is there any way to recover the user? or even restore everything to default?

You've got a (hopefully) valid backup config file. There is no other way to break into a FGT than using the maintainer access (physical access required).

Check the config file (text file) for gross mistakes, like missing routing section (at the end), and especially that the 'config system admin' section is complete and valid.

Then I would

- reboot

- interrupt boot sequence

- format flash disk

- reload the same firmware via TFTP

- reload the config

I would double check that admin is or is not present

show sys admin | grep admin

It would not hurt to see what other accounts are present at the same time.
