Custom Font Not Working

Site URL: https://www.marcofbruni.com/

I'm trying to add a custom font to my website but it doesn't seem to be working.

I have installed the ttf, woff and woff2 files and have used what I believe are the correct codes.

Would someone be able to help me figure out why this isn't working 😞

I also went back to see if the current Heading selected on my site is h1 and it is, so I'm a bit confused as to why this isn't updating.

You paste some characters into url, make font url doesn't exist.

Use this new code

@font-face {
    font-family: 'adam-medium';
    src: url(https://static1.squarespace.com/static/5e8ba2d8fe4f36648f68daf1/t/628e56e16660714b4393b1b1/1653495521774/Adam-Medium.ttf);
    src: url(https://static1.squarespace.com/static/5e8ba2d8fe4f36648f68daf1/t/628e56e57af3ea47ee4ff5c9/1653495525082/adam-medium-webfont.woff),url(https://static1.squarespace.com/static/5e8ba2d8fe4f36648f68daf1/t/628e56e7604b4b49b501505b/1653495527784/adam-medium-webfont.woff2);
}

h1 {
    font-family: 'adam-medium';
}
