Custom fonts not showing up on certain browsers?

Site URL: https://www.thanksliving2020.live/

Hi all,

I have a custom font embedded to a site I'm working on but my client is saying she can view the header font (LuckyDipCaitlin) on her phone but not on desktop. I can see it on Chrome and Firefox, but not on Safari. What should I do to fix this? Thank you in advance! 

@font-face {

    font-family: 'LuckyDipCaitlin';

       src: url('https://static1.squarespace.com/static/5f99e8ae3cb2f471f2b19e58/t/5fa72a67b75bcf39d65c6a0d/1604790887126/LuckyDipCaitlin.otf');

  }

h1 {font-family: 'LuckyDipCaitlin';}
h2 {font-family: 'LuckyDipCaitlin';}

@font-face {

    font-family: 'EBGaramond';

       src: url('https://static1.squarespace.com/static/5f99e8ae3cb2f471f2b19e58/t/5fa72aa8d9418b4912909f72/1604790953017/EBGaramond12-Regular.otf');

  }

h3 {font-family: 'EBGaramond';}
h4 {font-family: 'EBGaramond';}
P {font-family: 'EBGaramond';}
button {font-family: 'EBGaramond';}

The font file url doesn't exist. You should check again all link.
