Leak in Gas In Line at Oetiker Clamp

I tried using the googles but everything that popped up said that oetiker clamps don't leak

I had a leak-free set up when I went on a business trip for 5 days. Came back and got my beer into the keg and then when I grab the exact same hose w/ QD that has been sitting in the kegerator all week all of a sudden I have a significant leak at the QD barb-gas line connection.

Any tips or should I just go replace it completely?

Hi

If the clamp has worked it's way through the line or if the line has cracked - no fix short of replacing. Given that line is cheap, if it's old I'd replace it as the same time I replaced the clamp.
