In certain scenarios, you may find the need to access LabCollector or the scan server utility from a computer other than the one where it is initially installed, often referred to as client computers.

The primary computer or server where LabCollector or Scan Server utility is originally installed typically establishes an HTTPS connection. The successful establishment of this connection relies on the correct installation of security certificates during the setup process.

However, client computers may lack these necessary certificates, which can result in an error message such as ‘There is a problem with this website’s security certificate.‘ This error can lead to browsers blocking communication with the intended website.

To address this issue and ensure seamless and secure connections from client computers, it becomes imperative to install the root Certificate Authority (CA) certificate, particularly when dealing with self-signed certificates. Throughout this Knowledge Base, we will demonstrate the process of installing a root CA certificate. We will use the example root CA certificate, referenced as ‘rootCA.pem,’ for illustrative purposes.
