Anticipation for a mammoth event within the membership's historical past was dampened by a devastating defeat to Celtic within the Premiership title race on the weekend.
And the Ibrox facet weren't their standard vibrant continental selves on the Estadio Municipal de Braga.
They didn't vogue a possibility of observe and have been undone by the identical slack defending which allowed their metropolis rivals to tug clear domestically on Sunday.
Rangers now face one other monumental night at Ibrox as they bid to rescue their quest to succeed in the final 4.
Van Bronckhorst drafted Glen Kamara, Scott Arfield and Style Sakala into his facet, the latter enjoying by way of the center following the information Alfredo Morelos' season is over.
And it was the guests who threatened first, with Sakala snatching at a rebound after Kent had been performed in and denied by a swarm of pink and white shirts.
The tempo of that pair was clearly spooking Braga and Rangers had the higher of the opening exchanges with out troubling Matheus within the residence aim.
However regardless of that menace, they got here inside a whisker of going behind earlier than the half-hour mark.
Rangers didn't take care of a deep cross and the ball broke to Horta to slam in opposition to the submit with the aim at his mercy.
Horta did have the ball within the internet a minute later, however the aim was dominated out for a foul on Ryan Jack within the build-up.
However, it was a warning for Rangers as they barely escaped a sloppy spell with out punishment.
It was one they didn't heed.
Once more it was woeful defending - Leon Balogun taking a swing and a miss at a unfastened ball to permit Ruiz to manage and hearth previous Allan McGregor.
Rangers might hardly declare Braga didn't deserve the benefit and it was one they sought to press residence after the break.
Yan Cuoto was notably effervescent on the proper flank however the guests, to their credit score, noticed out an early second-half push to re-establish a presence once more.
The issue was, it was a slightly benign one.
It took the introduction of Kemar Roofe, Joe Aribo and Borna Barisic to construct some ahead momentum as Rangers lastly started to push ahead with function.
They might properly have equalised from a nook had Connor Goldson directed his free header on course from an admittedly tough angle.
He then laid off for Calvin Bassey from one other set-piece however his strike was blocked by Braga our bodies placing themselves on the road and it proved to be the guests' ultimate probability.
On the road, as a matter of reality, is the place Rangers should now lay all of it subsequent week.
5 speaking factors
The dream on a knife edge
Rangers are likely to solely take part in blockbusters on this event however there have been all too few indicators of a spark on this event.
A Goldson header apart, it is troublesome to instantly recall any clear reduce probabilities for Van Bronckhorst's facet.
Because it was in opposition to Celtic, there was loads of endeavour however too little invention from the lads in Mild Blue. As time progressed,
The result is that their Europa League dream has been left on a precarious knife edge forward of subsequent week's return leg at Ibrox.
Rangers at residence on this competitors, nonetheless, means you possibly can by no means rule them out and so they might give the house crowd that blockbuster their travelling followers have been denied right here.
Gio's adjustments do not ship
The Ibrox boss mentioned forward of kick-off he was placing belief within the depth of his squad as Aribo, Roofe and Ramsey made method for Arfield, Kamara and Sakala.
Trusting in depth was at odds with how Van Bronckhorst used solely two subs from a doable 5 in defeat to Celtic and it was the identical pair who got here off the bench there who began right here, with the addition of Kamara into midfield.
The omission of Ramsey, who was a optimistic at Ibrox on Sunday, was notable - particularly contemplating how quiet Kamara was.
Sakala, too, did not look notably snug as a central striker and regardless of threatening in behind early on, could not make a big mark on proceedings.
Defending prices Rangers once more
Rangers gave away two dreadful objectives in opposition to Celtic and so they have been simply as dangerous right here.
They got a stern warning when Horta's aim was dominated out by VAR, however the usual of defending advised it would not be lengthy till they made one rely.
Balogun's mistake was a foul one, though admittedly it was very ruthlessly punished.
However for those who proceed to make such errors then you possibly can solely count on to pay.
It is all a far cry from the Rangers defence which gave so little away final season.
Spectacular Braga
The final time these sides met there was an actual Jekyll and Hyde really feel about Braga.
They have been wonderful for a lot of the primary leg earlier than being swept up within the Ibrox cauldron after which have been principally in all places within the return leg.
And regardless of Rangers beginning on the entrance foot right here, Carvalhal's facet grew and grew into proceedings.
Yan Couto at right-back, who very almost joined Celtic in the summertime, was notably spectacular down the flank, inflicting Rangers all kinds of points.
An odd feeling for an enormous event
For what was, realistically, the most important evening within the membership's historical past since 2008, there was a considerably muted feeling round this all-important 90 minutes.
That was, after all, due to what occurred on the weekend.
Europe is monumental to the membership however the ache of all-but giving up their Premiership title forged a shadow over the build-up, with as many pre-match questions nonetheless centring on defeat to Celtic because the prospect of beating Braga.
That cloud darkened additional when Braga deservedly took the lead earlier than half-time, with Rangers leaving it till late within the second interval to mount a significant cost.
And though it proved fruitless, there's nonetheless every part to play for on this tie.
