    When using Chrome browser to perform HTML 5 Remote Control to an Agent machine, a security warning shows "Your connection is not private. Attackers might be trying to steal your information from [core server name] (for example, passwords, messages, or credit cards). NET::ERR_COMMON_NAME_INVALID". While legacy Remote Control has no problem connecting to the Agent machine.

    This error is seen because the browser is referencing the self-signed certificate that LDMS/EPM generated on the core server, and copied down to the clients. However the certificate is not installed properly on the client as a trusted certificate, so this prompt appears.


    Possible Workarounds:

    1. Add RCHTML5 certificate to the client's Trusted Root Certification Authorities store. Detailed steps can be found on this article.

    2. On the page with the security warning, click on Advanced>Click on Continue. This would ignore the security warning and continue to visit the site.
