Launceston director of rugby Neil Bayliss says his side must face up to their shortcomings after failing to make a seven-point half time lead count in their 35-22 defeat by Henley Hawks.
The Cornish All Blacks led 19-13 at the break and were 22-20 ahead with 10 minutes to go before conceding five penalties to miss out on a bonus point.
"We need to have a long took at ourselves," Bayliss told BBC Cornwall.
"They've got a cracking side and they dominated us for the last 20 minutes."
Launceston were on a high after winning 35-22 at Dings Crusaders last week and Jake Murphy, Sam Chapman and Jamie Salter all scored first-half tries.
But they could only muster a Kieron Lewitt penalty after the break to leave Bayliss frustrated.
"First half, we looked good for our money and comfortable, but we came out in the second half and I'm not sure if it's fitness or what, but that's when Henley capitalised on us and their fly-half kicked five penalties and won them the game," he said.
"We wanted to take this as a stepping stone against one of the best teams in the league and we fell 10 points short and that's something we need to address."
The loss saw Launceston slip to 10th place in the National Two South table.
