Zwave JS : port is already allocated

Installation
1

Hello,
I am trying to install Zwave JS but I have this error in the supervisor logs.
I don’t know what to do … Can you help me?
Thank you

21-03-12 20:50:22 ERROR (SyncWorker_2) [supervisor.docker] Can't start addon_core_zwave_js: 500 Server Error for http+docker://localhost/v1.40/containers/9ad4acb77cd444f8036a38006a271c3543de84229a6c8d6cfbdb47cf169f3645/start: Internal Server Error ("driver failed programming external connectivity on endpoint addon_core_zwave_js (d346fdd6c0ea581bc7dc4a3e178771b22fefa95b92ece41a5a8e07f22fa0d45b): Bind for 0.0.0.0:3000 failed: port is already allocated")

I use Hassio.

What is using port 3000 already?
You either need to change that or choose a different one for zwave js

I installed Zwave JS To MQTT then uninstalled, then installed Zwave JS … and I feel like Docker missed a step and keeps port 3000 mapped.
I tried to change but then when I install the integration, unable to join the ws on port 3001 (for example).

Are you sure zwjs-mqtt is uninstalled fully

I felt … I rebooted the host, so docker and was able to cleanly reinstall Zwave JS to MQTT …
HA is really very slow in his actions and does not always give feedback …
