NiFi ListenHTTP Failed to bind to 0.0.0.0

[#1]

Hello,

while attempting to start ListenHTTP (port=10000) on a fresh cluster, I obtain the following error. Do you know what to change to get it work?

ListenHTTP[id=6222ab5d-0177-1000-ffff-ffffaeaba266]
Failed to properly initialize Processor. If still scheduled to run, NiFi will attempt to initialize and run the Processor again after the 'Administrative Yield Duration' has elapsed.
