No endpoints found. Please try to use different discovery server or specify the OPC UA server endpoint manually. I encounter this problem while adding a data source during PI Connector configuration. Can you please help us resolve?

While configuring data sources for a connector in PI Data collection Manager. I tried to discover available endpoints after entering the server endpoint URL,

In our case: opc.tcp://AW8001:48031

But I get this error "No endpoints found. Please try to use different discovery server or specify the OPC UA server endpoint manually. "

​

I have attached the below snapshot of the error.
