Dear Thomas
For analysis, please send a support bundle to support@paessler.com. This can be done by using the PRTG webinterface, menu Setup / Contact Support. Please include a description of the issue with the disconnected probes.
The support bundle contains a selection of important log files and an overall status overview which provides us a good starting point for analysis.
