The CMS hosting doesn’t allow static page hosting. That is I can’t have http://www.foo.com/something serve a json or text file.
Our DNS has a CNAME for www to proxy-ssl dot webflow dot com. So I deleted that and pointed an A record for www to my server’s ip.
I setup a reverse proxy in golang to that same proxy-ssl.webflow.com address and use it for everything except that one static file. But it doesn’t work. Every hit thru the proxy is a 404 this way.
