Dear Mohamed,
At least you have an odd number of electrons but you do not specify a
spin polarisation in your input. The system might well be a doublet or a
quartet...
You can also try using with the smearing/broadening of the occupation
numbers: It does not harm, and if and when the self-consistent cycle has
converged you can investigate if there is indeed a gap between the
occupied and unoccupied orbitals or not.
(Usually in a system with vacuum I use the mixing mode 'local-TF')

Dear all I am tried many times to do relax step for GQDs structures using an
attached input file but I faced the error attached also here. I am used the
same input file for the same structure in case of oxygen passivation ( not
nitrogen ) and no errors appeared.
thanks
