 ## Advanced Features
 
+### TLS Handshake Optimization
+
+The enhanced `PortProxy` implementation includes significant improvements for TLS handshake handling:
+
+- Robust SNI extraction with improved error handling
+- Increased buffer size for complex TLS handshakes (10MB)
+- Longer initial handshake timeout (60 seconds)
+- Detection and tracking of TLS connection states
+- Optional detailed TLS debug logging for troubleshooting
+- Browser compatibility fixes for Chrome certificate errors
+
+```typescript
+// Example configuration to solve Chrome certificate errors
+const portProxy = new PortProxy({
+  // ... other settings
+  initialDataTimeout: 60000,            // Give browser more time for handshake
+  maxPendingDataSize: 10 * 1024 * 1024, // Larger buffer for complex handshakes
+  enableTlsDebugLogging: true,          // Enable when troubleshooting
+});
+```
+
 ### Connection Management and Monitoring
 
 The `PortProxy` class includes built-in connection tracking and monitoring:
 
-- Automatic cleanup of idle connections
+- Automatic cleanup of idle connections with configurable timeouts
 - Timeouts for connections that exceed maximum lifetime
 - Detailed logging of connection states
 - Termination statistics
+- Randomized timeouts to prevent "thundering herd" problems
+- Per-domain timeout configuration

+## Troubleshooting
+
+### Browser Certificate Errors
+
+If you experience certificate errors in browsers, especially in Chrome, try these solutions:
+
+1. **Increase Initial Data Timeout**: Set `initialDataTimeout` to 60 seconds or higher
+2. **Increase Buffer Size**: Set `maxPendingDataSize` to 10MB or higher
+3. **Enable TLS Debug Logging**: Set `enableTlsDebugLogging: true` to troubleshoot handshake issues
+4. **Enable Keep-Alive Probes**: Set `enableKeepAliveProbes: true` for better connection stability
+5. **Check Certificate Chain**: Ensure your certificate chain is complete and in the correct order
+
+```typescript
+// Configuration to fix Chrome certificate errors
+const portProxy = new PortProxy({
+  // ... other settings
+  initialDataTimeout: 60000,
+  maxPendingDataSize: 10 * 1024 * 1024,
+  enableTlsDebugLogging: true,
+  enableKeepAliveProbes: true
+});
+```
+
+### Connection Stability
+
+For improved connection stability in high-traffic environments:
+
+1. **Set Appropriate Timeouts**: Use longer timeouts for long-lived connections
+2. **Use Domain-Specific Timeouts**: Configure per-domain timeouts for different types of services
+3. **Enable TCP Keep-Alive**: Ensure `keepAlive` is set to `true`
+4. **Monitor Connection Statistics**: Enable detailed logging to track termination reasons
+5. **Fine-tune Inactivity Checks**: Adjust `inactivityCheckInterval` based on your traffic patterns
