The retransmissions are all SYN packets to outside IP addresses on port 443. I can reach these IP addresses on port 443 and (at least) 8.8.8.8 is one that is most probably up all the time. So something in your network must be blocking/dropping these SYN packets.

Are you able to use a VPN like Cloudflare Warpor any other. If so, does HTTPS access to https://dns.google work over the VPN?

According to wikipedia, there might be Internet censorship in Egypt. One possible way is to regulate DNS, so that could explain HTTPS access to google (and other DNS servers) to be denied.

There has been many issues with VPN-- although did not check this now. Howevere, it did or used to stream to DNS providers successfully. As per Egypt-- from my experience it works okay on many WIFIs.

If it works on many different WIFIs, then can you tell me more about the network on which you see these retransmissions and failing connections? I expect this to be a problem local to that network then.
