When I create flow from outside the salesforc community, flow creates. But When I try to create flow from salesforce community. it gives me the error [Visualforce Remoting Exception: IO Exception: Unable to tunnel through proxy. Proxy returns "HTTP/1.0 404 Not Found]
It calls the official Salesforce Metadata SOAP API end points. Can anyone help me to out this?
