Vugen script reply Error - Failed to connect to server "xxxxx.com:443": [10060] Connection timed out

I am able to access the application manually and able to record a Web(HTTP/HTML) script using Vugen11.52 but while replying a script, getting “Connection timed out” error.
Environment: Vugen 11.52, IE11, RTS: Proxy-Obtain the proxy settings from the default browser

Tried below options but no luck.

• Increased HTTP Request and Keep Alive Timeouts
• Added web_set_sockets_option("SSL_VERSION", "TLS");
• Replied script with “Winnet reply instead of Sockets”, error: "HttpSendRequest" failed, Windows error code=12029 (cannot connect) and retry limit (0) exceeded for URL=”

 Any suggestion would be highly appreciated.
