I bought/installed the NAS F2-221 in September 2021 for a customer.
The plan was to automatic startup at 8:00 PM and shut down at 04:00 am.
I ran on the problem that the device switched off after some minutes after switching it on manually. I tried that some times.
I removed the option to automatic start up and shut down and the device ran with no break until last Friday (dec-04 '21).
Today at high noon I begged the customer via phone, to switch on the device. Now at 8:00 PM I tried to work with it from remote, but it switched off again.

Where can I begin to find the error? I have to drive about 200 km (124 mi) to visit the customer. So I can't try this and that and fiddle around.
I have several of that devices (F2-210/220/221) for my customers and one for myself. I never had such problem (ok, one time in the past I had configured the wrong time zone ).
Before you ask: The firmware is actual and original.

Thanks and greetings

There have been a few reports of "misbehaving" fans.
I would monitor the temperature, as that could be the root cause of your shutdowns.

The general solution is to set the fan to Medium, rather than Auto

Thanks for the replies.

I will try out and give a response.

Also check the clock battery. Probably ok but might be losing the time.
