azure – unable to connect onpremisesql to adf

Cannot connect to SQL Database. Please contact SQL server team for further support. Server: '', Database: '', User: ''. Check the linked service configuration is correct, and make sure the SQL Database firewall allows the integration runtime to access. A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) The certificate chain was issued by an authority that is not trusted

I have tried install the self-hosted integration runtime and unable to connect the on-premise SQL server in ADF.
