The log file has some interesting bits in - this is *pronbably* when it vanished. It mentioned a netgear UPnP device - but I'm *certain* this servrer is plugged into an unmanaged basic netgeat GS108 type switch, and from there to a Draytek router. No managed netgear I'm aware of
(though will look under desks next time I'm there!)

No, service running OK, and UI was actually running, but just "powered off". Same on both servers. Restarting service made no difference. Only was was to click "poower on" button on UI
Do you know if this can be done from a script/tool/command line?
Interestingly, on the server I posted the log yesterday, I did a LAN scan and found an old netgear router being used as just an AP - e.g. wifi AP connected to LAN switch. No broadband connected. It was on a different subnet and in theroy the server should not know it exists, but it appears the router was advertising uPnP, and indeed there were uPnP sessions grabbed by the router from the server (!). So I've disabled uPnP on that router as if it was getting in the way, of course something would break. If it still crashes I'll get it unplugged. The log above mentions Netgear uPnP hence feeling confident.
The other server that powers hamachi off has a different log and no mention of a crash so can't figure that one out....
We have the same on our client computers. Hamachi poweroff himself. Only with a Power-on click it logged on again. I also don't get it why there is a power on/off button if you run hamachi by services. The services run, but a client can overrule by clicking power-/loggoff button. Bye bye connection.
We also asked support to change this or make a command option to auto poweron hamachi interface we can builld in a script. But no support from here, and we also have a paid account with 999 clients.
have the same Problem spread over many Companys , some Clinets and Servers switches semselfes to Offline like somebody Push the Power Off Button. Everything is Licenced and Paid. This is a Often Common Problem.
