…i had yesterday also trouble on updating to 4.0.2 (with docker) and with the bindings (upnp too). See https://community.openhab.org/t/update-from-oh4-0-1-to-4-0-2-docker-results-in-error-handler-for-99-of-openhab-things/148763/2 My solution was cleaning userdata/tmp and userdata/cache and then go to bindings and download all bindings i had before manually again. Maybe this helps someone. After that all was fine
