PRTG Core Server Service stops at 12:42 AM (Eastern Time zone).

Hello there,

I have a strange issue. For some reason the PRTG Core Server Service stops at 12:42 AM (Eastern Time zone). I have updated to the current version and its stable (PRTG Network Monitor 17.1.30.1681 x64).

I have a colleague using an older version “16.4.28.7421”, and he doesn’t have this issue.

Dear Ahmed Omar,

The Core Log shows a shut down during the night here:

Dear Ahmed Omar,

We can see no issues from PRTG's logs with the Windows services it depends on. However, that cannot really be logged from within PRTG, so you will have to check this yourself if those services were shut down by any chance.
