How to set up a proxy server to connect to WhatsApp
When people around the world are blocked from using WhatsApp, volunteers and organizations can create proxy servers that help people re-establish connection to WhatsApp and communicate freely and securely.
To help people reconnect to WhatsApp, you can set up a proxy using a server with ports 80, 443 or 5222 available and a domain name (or subdomain) that points to the server’s IP address. Detailed documentation and source code are available on GitHub here.
Consider sharing these addresses privately with users who are unable to connect directly to WhatsApp.
