I don’t know
What are the steps to reproduce the issue?
We transferred the domain kr-labs.com to Cloudflare, added 2 DNS records - @ and WWW, directed them to the dummy IP 192.0.2.1, and then created a Page Rule for the 301 Forwarding URL from kr-labs.com/ to other our domain. But redirect not working. This is surprising because we have used this feature many times in the past. Please help us find the cause.
