Cloudflare is a huge part of the internet. Often they won't respond and it appears that for whatever reason, their IP range is blocked in Egypt. We probably get 10 support emails per week. I contacted Cloudflare and they simply said there is nothing they can do.
Blocking cloudflare ip addresses means that half of the internet wouldn't be accessible from Egypt. its closw to blocking port 443 because some people use DNS over https.
disclaimer: I'm Egyptian living in the US.
Apparently there is a pool of IP's that Cloudflare use for their CDN and some of them are blocked in Egypt. If you are unlucky enough to be one of the websites that is using that IP, it's blocked. Apparently they rotate them, but I haven't seen it yet, so chances are, when they do rotate them, more will be blocked.
