Look for the current IP address of the Server in the local network. The current IP address can be found as explained in the “IP address” tab. Copy this IP address and replace the “xxx.xxx.xxx.xxx” in http://xxx.xxx.xxx.xxx:8000/dashboard/app with this address.
Please make sure that your computer and the Server are on the same network by for example checking the network settings of your computer or by pinging the Server’s address. It is also necessary that both clients can directly connect to each other. Some network configurations do not allow such connections even when both computer and Server are on the same subnet.
