Custom font not working - Cache cleared, https used, woff used

[archerthefox]

I’ve cleared the cache, the font is woff format and it’s uploaded as a https url.

I can’t find anything else that I should be doing.

Hello @archerthefox,

Thanks for writing to us.

I checked the given set URL it seems that there is some mixed content issue. It seems that the URLs are not fully replaced while moving the site from staging to production or from HTTP to HTTPS site and that causes the Mixed Content issue [ HTTP and HTTPS ] blocking to load of the Font files. I would suggest you replace the URL properly and check this again, there are many URL replacement Plugins available in WordPress that help you to replace the URL.
This article will be helpful in this:https://www.wpbeginner.com/plugins/how-to-update-urls-when-moving-your-wordpress-site/

Also, remember that the exact URL should be mentioned in Setting > General, WordPress Address, and Site URL, including the protocol i.e. HTTP/HTTPS.

Hope this helps.
Thanks
