you haven't specified the font name in your style sheet, it's still in there as "font-name". Probably just didn't spot you had to change it in two places from where you copied it in.
change that to corinthiago and you'll probably be OK. the reason it works on your laptop is probably because you've got the font installed locally.
so something like this.
@font-face {
font-family: corinthiago;
src: url(https://static1.squarespace.com/static/60c04bccb3eb927f554f9eeb/t/60cec441871e18034ea73d58/1624163393990/Corinthiago.otf)
}
h2 {
font-family: corinthiago, "Balboa Plus Inline";
}
