Hi, I tried to add Cloudflare’s IPs to my Cloudflare rule, but some ips are allowed but some other are not. Any idea why this could be happened?

Hi @tmb13
I’ve just tried to add every CloudFlare IP to the DO Firewall - and it works, but you have to wait about 1 second before hitting Enter-key otherwise it sometimes adds
All IPv4.But looking at the picture, it looks like there’s a space or another spacial character in front of
104.16.0.0/12(marked as red). Use the plain text lists instead.If anyone else is interested in adding CloudFlare, then you can find the lists here: https://www.cloudflare.com/ips/ - I would recommend using the plain text lists.
