## 🔐 Certificate Installation (for HTTPS Traffic Capture)

* When capturing HTTPS traffic (from browsers or mobile devices), Loadmill installs a local root certificate to decrypt HTTPS traffic
* During installation, accept the certificate prompt to allow HTTPS capture
* If using for mobile capture: export and install the certificate on the mobile device via Wi-Fi proxy configuration
* Ensure both desktop and mobile device are on the same Wi-Fi network for proper capture

## 🌐 Network Configuration

* Allow outbound HTTPS (TCP port 443) to Loadmill’s cloud endpoints
