Client-Side Handshake Solutions

Client-Side Handshake Solutions

Client-side issues include outdated browsers, aggressive firewalls, or system clock problems. Update browsers to support modern TLS versions. Corporate firewalls sometimes interfere with handshakes by performing deep packet inspection. Temporarily disable security software to test if it's causing failures.

For applications and APIs experiencing handshake failures, explicitly configure TLS versions:

import ssl
import requests

# Force TLS 1.2/1.3
requests.get('https://example.com', 
    verify=True,
    timeout=10,
    headers={'User-Agent': 'MyApp/1.0'},
    # Configure SSL context
    ssl_context=ssl.create_default_context()
)
