The problem is, there is no secure solution that doesn’t involve an SSL certificate for your server that is running Panorama Server.
In your HTML code, I’m sure the action tag in the form you are submitting is something like this:
To be secure, that tag needs to be
http:. But you can’t do that unless your server has an SSL certificate.
What’s happening now is that when the Submit button is pressed, the browser is sending a message to your server using
http: protocol, which is an insecure protocol (in fact it has no security at all, it’s just plain text). The browser notices that an insecure protocol is used, and it complains. But even if it didn’t complain, the communication would still be insecure.
If it doesn’t matter that the communication is insecure, simply make the entire page use
http:, then the browser won’t complain. But the user won’t see a lock indicating a secure connection.
