PRTG Remote Probe service stopping

We have a few remote probes (all up to date) on windows Server 2016 and recently we have had a problem with the service stopping randomly.

When we remote in and restart the service, everything seems normal.

Is there anything we can do to solve this problem?

Dear Phillip,

in order to check what is going on, please check the Windows Event Log on the remote probe computer.

Please also check the probe log files, usually found in "C:\ProgramData\Paessler\PRTG Network Monitor\Logs (System)" in order to check PRTG's side.

If the issue turns out to be more complex, feel free to contact us at support@paessler.com.

Thanks Arne,

I have check the PRTG log and from my reading it appears to be Time related. See log below. Can you shed any light on why the service would shutdown due to a time change??

Dear Phillip,

the probe stopping is probably not tied to the time change. Please check the Windows Event log on the probe, and/or the PRTG core service log for entries which could be related to the probe restart.
