City Women lost their first league fixture of the season to top of the table Actonians, in a 2-1 defeat at The Nest.
A first league goal from Eloise Morran wasn't enough to hold onto an equaliser in the first half and the defeat is the first at The Nest in almost a year.
Andy Cook named an unchanged starting 11 from the 1-0 win over Cambridge United in the FA Cup last weekend.
City started very much on the front foot, looking very comfortable down the right where Millie Daviss was settling into her role higher up the pitch.
It was the visitors, however, who found a breakthrough in the early stages, as a misplaced pass allowed Actonians to break through the City defence and Hana Lalani shot from distance to find the bottom corner of the net.
Following the goal, City were still on the attack, with some great play from Natasha Snelling to allow Tamsin Medd-Gill a shot from the edge of the area but her effort dragged wide.
After further controlled play from the Canaries, the home side found the all-important equaliser through Morran, who lobbed Elisa Dogor in goal on the half-hour mark.
Actonians found an immediate response though, Amina Haniff netting from close-range just after kick-off.
Holly Kennard thought she had the ball in the back of the net after she out-muscled Dogor in goal to snatch the ball and dribble into an emty net, but the referee disallowed it for a foul on the Actonians' goalkeeper.
Steady play continued for the final 15 minutes of the first half but City went in 2-1 down at the break.
Norwich's best chance of the second 45 came from more brilliant work from Kennard down the left side, surpassing three defenders to cut a shot in that hit the crossbar but Snelling couldn't get the rebound over the line.
Down the other end, Hope Strauss was required to do some excellent defending, keeping the visitors' top scorer Dior Knorr from taking a shot deep inside City's box.
Andy Cook made a quadruple substitution with 20 minutes left, introducing captain Megan Todd for her first league appearance of the season.
City were knocking on Actonians' door for the remainder of the game, withholding all possession from the visitors but none of their efforts could find a second equaliser.
