This is usually the result of Vugen not recognizing HTTPS data. Check to see if your web requests start with https. If they do, you will need to select the correct SSL version in the Port Mapping section of the Recording Options. From the Port Mapping Dialog, click on the Options button. This will open the Advanced Port Mapping Setting. On this dialog, you will select Enable auto SSL detect, and select the appropriate SSL Version. Then click on the Update Button, and then the OK button. You should now be able to record HTTPS envents.
