Selected Answer: B
Think its B: Firewall rules on the remote server block the client on port 443. • The server is up and running since other users can access the webpage. • The client can connect via Telnet and SSH, meaning general network connectivity is fine. • The issue is specific to HTTPS traffic (port 443), suggesting that a firewall rule is blocking the client’s IP.

Curl is using certification key, so there is some sort of TLS Client Authentication configured in the Remote Server. My answer would be C.

Selected Answer: C
The server may have increased security that is blocking the cURL request2. Even though the developer can ping the server and open a TCP socket with Telnet, the application layer security could still block specific types of connections, like cURL12.
