Hello Patrick, hello Chris we are having nearly the same problem. A monitored server was offline in Dashboard all the time. Tried to reinstall --> no change. Delete device from dashboard and reinstalled again. Device is activated and even connected to, (Test notifications and validating account is working to.) But it still doesn't appears in Dashboard or mobile app and so we aren't able to perform any action on this device. When i try to establish performance counters I'm getting this: This dll is belonging to EXTREMZ-IP AFP Services "Name der fehlerhaften Anwendung: PCMonitorManager.exe, Version: 4.7.6.704, Zeitstempel: 0x5598214a Name des fehlerhaften Moduls: ZIPPerformance64.dll, Version: 9.0.4.121, Zeitstempel: 0x546d2dc8"
