In this section, you can upload SSL Certificates for the LSLB farm using the Upload Certificate action. Clicking the Upload button will open a file upload form specifically for PEM certificates to be uploaded to the load balancer. Simply locate the certificate file on your local machine, select it, and proceed with the upload. Once uploaded, the certificate will be displayed in the list of certificates.
Note. Please ensure that you upload files only in .pem format.
Next step, see the certificate info.
