Unresponsive Gallery Hover with link

Hi! I am having a problem with my gallery hover with link as it is not responsive (cannot be clicked/redirected to the linked pages)

I have this code I found in this forum as well:

//Gallery Hover//
figure.gallery-grid-item {
    position: relative;
}
.gallery-caption {
    position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
  font-size:4em;
  color:white;
  
}


/* title */
.gallery-caption-content {
    position: absolute;
    left: 0;
    top: 0;
    right: 0;
    bottom: 0;
    display: flex;
    justify-content: center;
    align-items: center;
    z-index: 999;
    padding: 7%;
 
 
 }
.gallery-section .gallery-caption p {
  font-family: Lato;
  font-weight: 700;
  font-size: 21px;
  color: #fff
}

/* overlay */
.gallery-grid-item-wrapper a:after {
    background: #000;
    content: "";
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    opacity: 0;
    transition: opacity ease 200ms !important;
 
}
.gallery-grid-item:hover .gallery-grid-item-wrapper a:after {
  opacity: 0.40;}

/* remove gap */
figcaption {
    padding: 0 !important;
}
