Error -27778 : SSL protocol error when attempting to read with host

Add the following statement at the beginning of the script:
web_set_sockets_option("SSL_VERSION", "3");

This forces the SSL connection to the server to use version 3 of the SSL protocol instead of letting the server suggest a version during the connection handshake.

   B.  Add the following statement at the beginning of the script:

web_set_sockets_option("MAX_CONNECTIONS_PER_HOST","1");

This forces a single TCP connection from the Load Generator to the server under test, it eliminates the possibility of the server prematurely shutting down an existing connection and causing errors when LoadRunner sends data using that connection.

  C. If none of the above works, then use the WinInet Replay engine. To do so, go to Run-Time Settings -> Preferences -> Select "WinInet Replay Engine instead of Sockets (Windows Only)."

Error -27740: Overlapped transmission of request to “www.url.com” for URL “http://www.url.com/ProdApp/” failed: WSA_IO_PENDING

Overlapped transmission error occurs when a flex script is running for the first time in the controller. But the same script runs successfully in VuGen.

Solution: The transmission of data to the server failed. It could be a N/W, router, or server problem. The word Overlapped refers to the way LoadRunner sends data in order to get a Web Page Breakdown. To resolve this problem, add the following statement to the beginning of the script to disable the breakdown of the “First Buffer” into server and network time.

web_set_sockets_option (“OVERLAPPED_SEND”, “0″);
