fonts gone from portfolio website

Hello,

A number of fonts disappeared from my website hosted on portfolio. In particular, one which I used for a new logo last year and also used for headers on the website. The font appears in my Creative Cloud app and shows up in a browser font search, but when I try to search for it via portfolio it indicates "no font found with that name".

I'm hoping someone could give some helpful advice. The font is Milka from the Letterbox Foundry.

Thanks

Scott
