Cloudflare blocking IP (not even captcha)

We have an application server. Cloudflare blocking our IP address so we cannot download repos like deb.sury, yarn because they are using cloudflare protection. It is not even captcha - IP is blocked.

packages.sury.org:443 (172.67.182.150). - connect (110: Connection timed out) Could not connect to packages.sury.org:443 (104.21.18.148). - connect (110: Connection timed out)
dl.yarnpkg.com:443 (104.18.126.100). - connect (110: Connection timed out) Could not connect to dl.yarnpkg.com:443 (104.16.171.99). - connect (110: Connection timed out)

What can we do to unblock IP address and why CF blocked IP? We are using this server since few months and it is only front application to our customers system.

Cloudflare wouldn’t block an IP like this - you likely have a network connectivity issue.

Can you please provide a traceroute from your server to each of these hostnames? Can you also traceroute to 1.1.1.1 and cloudflare.com

OK so all of those traces show you can reach us - there is some ICMP loss on a couple of those IPs but not sure it’s important at this stage.

Can you try this:

curl -v https://1.1.1.1/cdn-cgi/trace
curl -v https://cloudflare.com/cdn-cgi/trace
curl -v https://1.1.1.1/cdn-cgi/trace
curl -v https://packages.sury.org/cdn-cgi/trace
curl -v https://dl.yarnpkg.com/cdn-cgi/trace
curl -v http://packages.sury.org/cdn-cgi/trace
curl -v http://dl.yarnpkg.com/cdn-cgi/trace
