Derek McInnes admitted Rangers are "not ready" to compete at Europa League level.
The Ibrox side drew the second leg of their third qualifying round tie against Jagiellonia Bialystok 1-1 at Ibrox, but crashed out 3-2 on aggregate.
It is their earliest exit from the competition since 2017, as McInnes' winless start as manager of the Ibrox side stretched to four games.
The Rangers fans made their feelings clear at full-time as boos rang around the stadium, something McInnes accepted.
"It was justified, to be honest. It wasn't good enough. What we served up, particularly second half, wasn't good enough," the former Rangers midfielder said.
"We need to be honest, the club's built for Europa League and Champions League and that's the intention, to get there.
"But I'm not sure the team is quite ready for it at the moment and it pains me to say that, to be honest, it does.
"We need to get more quality, we need to try and get more confidence out of the team."
Missing left-back Tuur Rommens and striker Youssef Chermiti through injury, McInnes moved to a back three among five changes from Sunday's defeat by Hibernian.
"I felt we had to make the game open and it was a bit too open at times in the first half. Gassama and Yakota playing as kind of effectively wing-backs, we were asking a lot of them at times," he added
"But I thought it paid dividends in terms of penalty box action, getting the goal.
"I thought we were good value for getting it one and a half-time, but I still thought that Jagiellonia had a couple of scares.
"Once again, it's not another 90-minute performance.
