  The extraordinary multi-TeV flare from 1ES 1011 +496 during February-March
2014 was observed by MAGIC telescopes for 17 nights and the average spectrum of
the whole period has a non-trivial shape. We have used the photohadronic model
and a template EBL model to explain the average spectrum which fits well to the
flare data. The spectral index $\alpha$ is the only free parameter in our
model. We have also shown that the non-trivial nature of the spectrum is due to
the change in the behavior of the optical depth above $\sim 600$ GeV
$\gamma$-ray energy accompanied with the high SSC flux.
