Configuration > Overlays & Security > Custom CA Certificate Trust Store
EdgeConnect appliances are pre-loaded with the Mozilla root store, which contains the root certificates of public CAs. The appliance uses this root store for cryptographic verification when opening TLS connections to Orchestrator and Cloud Portal. If you wish to use a server certificate signed by a private CA, you must first upload its root certificate here.
Click Test Connectivity to Portal to validate that appliances can successfully connect to Orchestrator and Cloud Portal using the custom CA before clicking the Use Custom Certificate Trust Store check box.
This feature is commonly used if you have deployed a web proxy between EdgeConnect and Orchestrator or Cloud Portal or if you do not wish to purchase a certificate from a public CA.
