Cristiano Ronaldo missed a second‑half penalty on the night he became his country's record appearance holder as a hugely frustrating match for Portugal and their captain in Paris ended goalless against Austria to leave Group F wide open in the 2016 Euro Championship.
Portugal dominated large swathes of the first competitive meeting between the sides since 1995 but were almost caught out several times, in particular when Stefan Ilsanker forced a good save with a crisp low strike shortly after the restart.
Hungary now top Group F with four points, Portugal and Iceland both have two and Austria have one point.
It is situation which leaves all four in with a shout of reaching the last 16.
In other matches, Belgium thrashed Republic of Ireland 3-0.
Romelu Lukaku scored twice as Belgium recorded their first win at Euro 2016 and damaged the Republic of Ireland's chances of reaching the last 16.
After a goalless opening half, Lukaku scored the Belgians' first goal at the tournament with a neat finish from the edge of the area.
Axel Witsel headed in the second goal in the 61st minute, before Lukaku side footed home after a quick counter.
Iceland and Hungary were locked at 1-all in other match.
