---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

STEPS TO REPRODUCE

Echo dot 4th gen on wifi, node-red on wired computer.

EXPECTED RESULTS

You must be able to find devices, i supposed. I tried with mobile alexa app and echo dot

ACTUAL RESULTS

Maybe it is a problem with packets between wifi and wired computer.
