Thank you. This helped!
Solution:
I added the filter to functions.php and then loading locally font
by adding custom css:
/* open-sans-regular - latin */
@font-face {
font-family: 'Open Sans';
font-style: normal;
font-weight: 400;
src: local('Open Sans Regular'), local('OpenSans-Regular'), url('/wp-content/themes/pro-child/fonts/open-sans-v17-latin-regular.woff2') format('woff2'), /* Super Modern Browsers */
url('/wp-content/themes/pro-child/fonts/open-sans-v17-latin-regular.woff') format('woff'); /* Modern Browsers */
}
/* open-sans-700 - latin */
@font-face {
font-family: 'Open Sans';
font-style: normal;
font-weight: 700;
src: local('Open Sans Bold'), local('OpenSans-Bold'), url('/wp-content/themes/pro-child/fonts/open-sans-v17-latin-700.woff2') format('woff2'), /* Super Modern Browsers */
url('/wp-content/themes/pro-child/fonts/open-sans-v17-latin-700.woff') format('woff'); /* Modern Browsers */
}
/* lora-regular - latin */
@font-face {
font-family: 'Lora';
font-style: normal;
font-weight: 400;
src: local('Lora Regular'), local('Lora-Regular'), url('/wp-content/themes/pro-child/fonts/lora-v14-latin-regular.woff2') format('woff2'), /* Super Modern Browsers */
url('/wp-content/themes/pro-child/fonts/lora-v14-latin-regular.woff') format('woff'); /* Modern Browsers */
}
/* lora-700 - latin */
@font-face {
font-family: 'Lora';
font-style: normal;
font-weight: 700;
src: local('Lora Bold'), local('Lora-Bold'), url('/wp-content/themes/pro-child/fonts/lora-v14-latin-700.woff2') format('woff2'), /* Super Modern Browsers */
url('/wp-content/themes/pro-child/fonts/lora-v14-latin-700.woff') format('woff'); /* Modern Browsers */
}
