I've got PRTG running on Server 2016.
Both core and probe service run on this box. Core is running fine and the web interfaces launches etc.
On the 15th the core and probe service restarted (for no obvious reason? This is something that happens occasionally, I don't think it was an update and the server itself didn't restart).
Anyway, after the core service successfully started I just get the following from the Probe service:
Error 15/05/2018 12:13:12 PRTGProbeService 0 None Service failed on start: Access violation at address 00B6878C in module 'PRTG Probe.exe'. Read of address 00000074 Error 15/05/2018 12:13:12 PRTGProbeService 0 None Can not start probe: Could not load SSL library.
This continues after rebooting the server itself.
Looking into it a bit further the restart on the 15th indicated 5 days uptime. The last Windows update was installed on the 10th so I'm guessing something there has caused me problems, however the patch notes don't offer anything obvious that might be causing the problem.
Any thoughts on how best to proceed?
