Rosler saw his Leeds side collapse at Ashton Gate, but it all started so well as goals from Mirco Antenucci and Chris Wood had Leeds 2-0 up away from home.
However, a remarkable late double-salvo from Kieran Agard and Aden Flint saw the Robins haul themselves back and earn a point, to the shock of Leeds fans everywhere.
The draw means that Leeds have yet to win a league game under Rosler, with three draws from three games - yet they were mightily close to claiming all three points at Ashton Gate on Wednesday night.
Speaking to LUTV after the final whistle, Rosler explained why he was happy regardless of the draw - and revealed what his message to the squad was following their collapse.
"They put everything in," said Rosler. "And this why I'm very happy. I'm very happy with the way they are putting in. You can't ask for anything more than that. We have to build them up now, and the players have to build themselves up, and we go again on Saturday. We need the crowd, we need fantastic support to push my players forward to overcome this 90 minutes and hopefully bring the first win."
"It was very, very close. I said to the boys, 'We are knocking on that door, harder and harder, and eventually the door will open up for our first three points," he added.
Leeds have little time to dwell on their capitulation, as they face a Yorkshire derby on Saturday, with Sheffield Wednesday arriving at Elland Road for a huge clash.
After three straight draws in the league - as well as a draw against Doncaster Rovers in the Capital One Cup before losing on penalties - Leeds are desperate for a win, and beating rivals Wednesday would be the ideal way to kickstart their season.
