When you replay an SSL encrypted script in Vugen, It fails with the following error;
Error -27778: SSL protocol error when attempting to connect with host "<Certificate Server>", Snapshot Info [MSH 1 2] [MsgId: MERR-27778]
The correct SSL server, Cipher and version was already set according to the document Error: "Cannot connect to remote server" in the Recording log when recording against HTTPS sites.
An openssl verify command against the .pem file included in the script directory prints the following error;
"C:\Program Files (x86)\HP\LoadRunner\bin\openssl" verify "C:\<Script Directory>\<PEM File>.pem"
...
error 20 at 0 depth lookup:unable to get local issuer certificate
This error shows that there is a certificate hierarchy which was not included in this .pem file.
You need to add all the certificates in the certificate hierarchy for the SSL certificate to a .pem file (e.g. CAs.pem) and
include this .pem file by adding the following line at the beginning of the script:
web_set_sockets_option("LOAD_VERIFY_FILE","CAs.pem");
