Usually that means that you already have node red running. Make sure you stop node red before trying to start it again.

uibuilder showing `0.0.0.0` as its IP address is NOT a uibuilder issue and isn't the reason Node-RED won't start.

uibuilder is showing as available on 0.0.0.0 because that is what Node-RED has been set to work on. It means that Node-RED's web servers are set to be available on all network interfaces on the server. uibuilder is, therefore, following along. This is the default setting for Node-RED on Linux devices.

As Colin has said, the failure is due to you already having port 1880 in use - almost certainly because Node-RED is already running when you try to start it again.
