Something seems wrong with your nginx config (or whatever interface you used to define the redirect)
When I run
curl -I http://bookserf.com/ I don’t get a 301 redirect to bookserf.webflow.io. I get a 503 error with a HTML page with a frameset that is trying to encapsulate your free bookserf.webflow.io page.
<html><head><meta name="viewport" content="width=device-width,initial-scale=1"></head>
<frameset border="0" rows="100%,*" cols="100%"
scrolling="yes" noresize src="https://bookserf.webflow.io"><frame name="BottomFrame" scrolling="no"
Most likely, Webflow blocks its free webflow.io sites from being embedded like this in a frame. That’s probably why you are seeing “refused to connect”.
But, if you use a real 301 redirect, it works. Bitly uses a 301 and it works with your site: https://bit.ly/399bwnD
@tommyboy82 , your redirects are also not configured properly.
curl -I https://www.petrichorproperty.com returns a 403 error.
