Not sure how to fix this issue.

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.
