I tried changing canonical page settings and stuff, but now I think the problem is in DNS settings.
I have 2 A records consisting of non-recommended SSL IP addresses. as listed here https://university.webflow.com/article/troubleshooting-your-dns-settings#fix-your-dns-settings
Trying to use recomended ones makes my site 404.
CNAME is www -> proxy-ssl.webflow.com
