Upgrade 2.4 to 2.5 openHAB Cloud and Zwave

Not sure what is happening but maybe try installing the Amazon binding via jar file from either here:
https://openhab.jfrog.io/openhab/libs-pullrequest-local/org/openhab/addons/bundles/org.openhab.binding.amazonechocontrol/2.5.0-SNAPSHOT/

or the beta version at the top of page here:

Place the jar file in usr/share/openhab2/addons then restart OH.

As mentioned, I’m not certain that this will fix your problem but it’s worth a shot.
