So, that is the reason, your orders are open now, but at that time, during the VPS server restart, your positions were closed and re-opened and the subscriber's account closed the orders. I don't know why it didn't re-opened them as it should. Maybe it wasn't properly synchronized after your restart.
The answer is somewhere in your (and subscriber's) log files.
Maybe the restart of your VPS server, made the signal copying system to believe that you've closed your orders, because it couldn't detect them open, with your server down.
So, it closed the orders and then re-opened them upon synchronization.
You see there is usually something that isn't being told.
Where is your log of the event @Joseph John Kriel
We can't tell anything from that, its only a part of it and not at the time of the incident.
It clearly states signal disabled.
I don't see the server restart in that log.
Its says signal disabled on the signal provider's log, the signal subscriber should have a: signal enabled, message.
