You may encounter the below error in Vugen while replaying a web http/html script:
Error -27776: Server "x.x.x.x" shut connection during attempt to negotiate SSL session
This issue is caused due to LoadRunner using a different SSL version 2.0, however the environment uses TLS protocol.
Use this function at the begining of the script resolves the issue:
web_set_sockets_option("SSL_VERSION", "TLS");
