try to
1) decrease POTIM for the first step
2) choose a different ionic optimization algorithm.

well, before you changed you NSW tag of INCAR, I think that too few NSW steps caused the problem. the system simply cannot converge within 5 iterations.

Did you have the same error message when u increase NSW to 15?

as you have neither changed IBRION nor POTIM, you should not expect different results.
