This particular exception (SocketException 10013) indicates a client-side configuration issue, not a remote server problem.
Here’s why:
The message “access forbidden by its access permissions” means Windows or local networking settings are blocking the connection attempt — the program never even reaches the remote server (services.facepunch.com:443).
The server isn’t refusing the connection; your local machine is preventing it from being made.
Common local causes
Firewall or antivirus blocking outbound HTTPS connections for that executable.
Port 443 (HTTPS) blocked or restricted by group policy, VPN, or security software.
The app doesn’t have network access permission (especially if running in a restricted environment or sandbox).
@matt That’s where I’m confused because I have every sbox executable whitelisted but I still can’t seem to find the executable that seemingly passes an argument to something else to launch the actual client or editor.
