Launceston head coach Jimmy Tucker was "bitterly disappointed" after his side lost 29-26 at Bury St Edmunds.
The visitors led 19-12 thanks to Richard Friend, Ben Hilton and Jamie Salter's first-half tries, but the home side scored three times after the break before Friend got a second late on.
The match was Tucker's second since he took charge of the side earlier this month, having drawn with Southend.
"I'm bitterly disappointed, they deserved better," Tucker said.
"Our forwards put in a hell of a shift, worked really hard and I suppose we've got to give credit to Bury St Edmunds' defence, it held out really well.
"We had enough possession and enough territory to win the game and that's really disappointing, but the effort levels from the boys was excellent."
Winless Launceston are still bottom of National Two South, nine points off second-from-bottom Chinnor, but they have secured four points in their last two games, compared with three points in their previous nine matches.
"That's two weeks in a row we can say that we can be proud, but now we've got to convert the pressure and the spirit into victories.
"I can't comment on how much fight and go in them there was three weeks ago because I wasn't watching, I've just asked and they're delivering, but there's still more to give."
