error with the awesome font

I have an issue with this plugin. Last version 1.6.6 , last version of WP and last version of Woocommerce. When I activate it I have an error: Failed to load resource: net::ERR_NAME_NOT_RESOLVED because it tries to load https://mysite.urlhttps//use.fontawesome.com/releases/v5.5.0/css/all.css
The URL for the all.css is wrong because the url is attached directly to my site url.
