Help: Luke 3 Output Jack Wiring

Just had a frustrating experience trying to change my L3 output jack. I got a stereo barrel jack and connected the wires just as they were in the old jack, white to tip, green to ring, and the black bundle to ground. But when I fully insert my guitar cable into the jack there is no output, like it’s grounding out. But if I barely pull on the cable the guitar output comes alive.

Can anyone enlighten me? I’ve got a multimeter and with the cable out everything is open but with the cable inserted I have continuity between tip and ground and open between tip and ring.
