There are many possibilities, but the most likely one is exactly as it says - your program cannot connect to 10.10.34.35 Port 443. Firewalls, routing, DNS, or simply a mistyped IP address are all possible. Best way to diagnose this is to open Powershell and type

Test-NetConnection -Computer 10.10.34.35 -Port 443

This will test to see if your computer can connect to that TCP endpoint. If Powershell cannot connect then your problem is not in your C# but its a network issue.
