Amateur Student Needing help with Weapon Attachment

Hi, I am very new to Unreal Engine. I have followed the official Unreal tutorial (twin stick shooter tutorial) and I have created a gun socket that connects to the hand in the skeletal mesh of my hero character. On the preview screen, I see that the gun has successfully attached itself to the hand and it follows the animations applied. However, when I play the viewport, The gun is attached to the leg area of my character and does not move with the animation…I am not sure what to do or what I have done incorrectly, thank you.
