Public error: The remote certificate is invalid according to the validation procedure

I got this error when public to Orchestrator on-premise.
Please help. Thanks

Can you clarify when you are seeing that error message and where? It sounds like you are connecting to Orchestrator (Web UI, Robot?).

Have you configured a certificate for use and is that certificate or certificate chain trusted by the client computer you are connecting from?

If you are using a self-signed certificate, you will need to import it in every robot or client host. If you are on a domain make sure the certificate is signed by your Root CA or a trusted CA in the certificate chain.
