The warning message is displayed because we deliver QuickHMI with a self-signed SSL certificate. This certificate is not signed by an official certificate authority and therefore gives you this error. However, the connection is in fact encrypted and secure. The browser simply reports that it cannot check whether the server is who it claims to be.
If you do not want to see this message, you have two possibilites:
1. You can purchase an SSL certificate from a certificate authority or use a free of charge service. In both cases, you will receive a certificate that you must import into the Runtime Manager then. After that, you will no longer receive this error message.
2. You can set the QuickHMI certificate as trustworthy: You can configure your computer so that it recognizes the certificate issued and signed by QuickHMI itself as valid.
To do this, first save the certificate from the browser in a local file and then import the certificate into your "Trusted root certification authorities".
It is important that you use the host name that is also entered in the certificate for the connection in the browser.
