Trust a Self-Signed Certificate on Client Devices

If Sym3 Web is configured with a valid SSL certificate from a trusted Certificate Authority (CA), no further action is required on the client device. The web browser will automatically trust the certificate, and a secured connection will be established without any warnings.

But if the Sym3 Web is configured with a self-signed certificate, each client device must install and trust the certificate to establish a secured connection. If the certificate is not trusted, the web browser will warn the user that the connection is not private. You will be prompt with a message similar to this:

Install the certificate on your device.

To trust the certificate, open a web browser on your device and follow these steps:

Step 1: Open Sym3 Web

Navigate to the Sym3 Web using the server URL. For example https://172.1.2.3:4031 (Replace the IP address with yours)

The web browser should warn you that this connection is not secured:
