Thanks for you updates. As Jürgen wrote we thought we could fix the issue with a release last week and logs seemed fine (as well as succesfull Applet runs going up again), but as reports here suggest there is obviously still an issue.
Regarding “reconnecting”: (if not done already) please consider trying to disconnect the service and set it up completely new again, which may make a difference.
(Unfortunately this means you would also have to ser up the Applets again.)
