This is a very frustrating situation: setting up your (regular) store in FM, going to sleep, and waking up only to find out the client was closed during the night, without any error message. It happens on a daily basis, and it's driving me crazy. I'm running Windows 10. - Internet connection is stable (not using VPN). - Laptop never sleeps. However, it does turn off the display after some time- but that isn't the cause for the problem. The client stays connected. - Windows update has nothing to do with it, since the laptop doesn't perform a reboot, and also updates are not on a daily basis. - Laptop has a solid hardware, so the CPU heating up or RAM running out are ruled out as well. - No other programs are running during the night, except for Chrome with a few tabs (not too much). I'm sure I'm not the only one experiencing this, and I'd be thankful for a resolution. Many thanks!
