Azure NSG whitelist Cloudflare

Thanks for taking the time to read this query.

I have added all the IP’s associated with Cloudflare as listed on their website onto my NSG on Microsoft Azure to allow 443 traffic. Unfortunately , Cloudflare is unable to make through the NSG.

I was able to test this by adding a Any Any rule - that allowed Cloudflare traffic through. This means some IP addresses are not being let through the NSG.

Has anyone seen this before?
