If you receive an error message relating to the RPC network status, you may need to modify the network connection options.
Click the gear icon in the upper left. In the window that opens, confirm the Dash Network is MAINNET.
Click through the list of Connections and only check the connections that have an RPC port of 443. The old network connections were using port 8080 and no longer work. The old network connections can be removed or unchecked.
