  PKS 1830-211 is a known macrolensed quasar located at a redshift of z=2.5.
Its high-energy gamma-ray emission has been detected with the Fermi-LAT
instrument and evidence for lensing was obtained by several authors from its
high-energy data.
  Observations of PKS 1830-211 were taken with the H.E.S.S. array of Imaging
Atmospheric Cherenkov Telescopes in August 2014, following a flare alert by the
Fermi- LAT collaboration. The H.E.S.S observations were aimed at detecting a
gamma-ray flare delayed by 20-27 days from the alert flare, as expected from
observations at other wavelengths.
  More than twelve hours of good quality data were taken with an analysis
threshold of $\sim67$ GeV. The significance of a potential signal is computed
as a function of the date as well as the average significance over the whole
period. Data are compared to simultaneous observations by Fermi-LAT.
  No photon excess or significant signal is detected. An upper limit on PKS
1830-211 flux above 67 GeV is computed and compared to the extrapolation of the
Fermi-LAT flare spectrum.
