What steps should I take to resolve an SSL handshake failed error on a server?

Server-side troubleshooting involves verifying the SSL/TLS configuration. Ensure the SSL certificate is valid, not expired, and properly installed. Confirm that the server supports a secure and up-to-date set of SSL/TLS protocols and ciphers. Check the server's date and time to ensure accuracy. Review the server's firewall rules to allow HTTPS traffic (port 443). Consult the web server's documentation (Apache, Nginx, etc.) for specific configuration instructions. Examine server logs for error messages related to SSL/TLS.
