Socket connection times out for accepting data

[conorsexton]

Expected behavior

The connection to the open socket (for sending in data to source) persists as long as the application is running.

Actual behavior

The connection to the open socket times out (after an indeterminate period), and users can no longer post data to the source panel through port 3001.

The issue is made worse by the fact that the local server gives an OK 200 response even if the connection is timed out.
