Cam Link Blinks When Being Plugged In And Then Stops

This happens every time I try and plug it in. This has never happened and today I tried to change up my camera and it messed up now. I use the cam link to stream and my camera is a PANASONIC Lumix G7. I cannot get the camera to connect to my computer. When I connect it, the can link says no signal in the elgato software and does not show up in stream labs OBS.
