Novice help - fiber connection not working after move

Hi, I have two Cisco 3850 with fiber module that had a fiber connection between them. After moving one of the switches and re-routing the fiber, I am not getting a link light on the connection.

The opposite end of the fiber terminates to a patch panel where I am able to plug in another device and get link lights - which leads me to believe it’s not a physical fiber issue, but one with one of the switches. There are other ports on the fiber module that light up though.

Any ideas?
