Scroll Down Button and search glas not showing in web browser

Hi – I’m using a scroll down Arrow in a color section but the Arrow is not displayed in any Browser as well as the search glas in the main menu. It seems that there’s an issue with the entypo-fontello font.

(Reason: CORS request did not succeed).

I looked at https://kriesi.at/documentation/enfold/icon/#icons-are-showing-as-rectangular-boxes- and made the suggested changes to .htaccess but still the same issue.

Do you have any suggestion how I could resolve this?

Thanks
