All the sudden uploaded fonts are not working

Without any known changes on my end, the fonts on this site have stopped working for Headings, Site Title, and Navigation.  For some reason Paragraph fonts appear unaffected. 

Here's the CSS used to upload and claim fonts:

/*Font Add: Futura Condensed*/
@font-face {

    font-family: 'Futura Condensed';

       src: url('https://static1.squarespace.com/static/62cc73513ed8951429c55699/t/62ce0b869816d0338c174f8d/1657670534320/Futura+Condensed.ttf');

  }

/*Font Add: Futura PT Condensed Medium*/
@font-face {

    font-family: 'Futura PT Condensed Medium';

       src: url(https://static1.squarespace.com/static/62cc73513ed8951429c55699/t/62d0fc4ffb533d47877c48d8/1657863247716/futura-pt-cond-medium.otf);
  }

/*Font Add: Futura Medium*/
@font-face {

    font-family: 'Futura Medium';

       src: url('https://static1.squarespace.com/static/62cc73513ed8951429c55699/t/62ce0b869816d0338c174f8d/1657670534320/Futura+Condensed.ttf');

  }

/*Font Add: Futura Condensed Medium*/
@font-face {

    font-family: 'Futura Condensed Medium';

       src: url(https://static1.squarespace.com/static/62cc73513ed8951429c55699/t/62d0fb1dfb533d47877c308e/1657862941748/Futura+Condensed+Medium.otf);

  }

/** header font **/
.header-title-text {
  font-family: 'Futura Condensed';
  font-weight: bold;
  letter-spacing: .01em;
  font-size: 4em;
  text-transform: uppercase;
}

/** header navigation font**/
.header-nav *, nav.header-menu-nav-list * {
    font-family: 'Futura Condensed';
    font-weight: 400;
      letter-spacing: .01em;
    font-size: 1.1em;
}

/*******FONTS ASSIGNMENTs*****/
/******HEADERS***************/
h1 {
  font-family: 'Futura Condensed';
  font-weight: bold !important;
}

h2 {
  font-family: 'Futura Condensed';
  font-weight: bold;
}

h3 {
  font-family: 'Futura Condensed';
  font-weight: bold;   letter-spacing: .05em
}

/*********Paragraphs**********/
p1 {
  font-family: 'Futura Medium';
}

p2 {
  font-family: 'Futura Medium';
}

p3 {
  font-family: 'Futura Medium';
}

Any insight appreciated. The above code was working perfectly that past six months and all the sudden stopped...

Try adding !important after each line.

Eg.

h3 {
  font-family: 'Futura Condensed' !important;
  font-weight: bold !important;
letter-spacing: .05em !important;
}

Hi @bycrawford thank you. This works for the font-weight and letter-spacing, but has no effect on the font-family. So I'm still trying to figure this out.

Just checked - if you head to the source URL for the font: https://static1.squarespace.com/static/62cc73513ed8951429c55699/t/62d0fb1dfb533d47877c308e/1657862941748/Futura+Condensed+Medium.otf

It has been deleted.

You'll need to reupload your font file. Hope this helps!

@bycrawford this did the trick! thank you for following up (truly, so gracious). any idea how these files could have been deleted without my doing so? regardless, thanks for cracking the case!
