So looks like something is not quite stable with this system, but it still worked most of the time! > We will check when my colleague is back from home office, but this > might take some time. Sure. Seems to work now, so at least that's good, I guess. I still think this might be an issue here, or maybe the CRF is just flaky somehow? Don't have any experience with these kind of issues either, TBH. Anyway, glad it works again. johannes
