What happens is that GoDaddy support (a painful story there) have their own method (using forwarding with masking)which is counter to Webflow’s method of using proxy-ssl.webflow.com (and doesn’t work anyway).
This is a screen shot of my GoDaddy DNS setings
and this is a screenshot of my Project settings page.
Please help. Where is the legendary Cyberdave when you need him? All I got is Webflow support person who is happy accusing GoDaddy that “their software is not working”.
