The router has a frightening log

[FIN]

Does anyone know what's going on with the router? Periodically, this information appears in the log. At the same time, the Internet, wifi and time are lost

So your router rebooted .

You'll need to provide a lot better infomation if you want people to help you.

What router? What firmware version? What scripts are you running?

Your router has been rebooted for some reason. That's just a Boot log. The log is ok. You need to find something makes your router rebooted like a defective AC Adapter, a device which effects on your router something like that.
Possibility.
a defective AC Adapter > a connected device.
I hate AC88U. I think AC88U is a defect itself.

Reading LOGs are often very exhausting but I found something else which might need some attention:

Didn't anyone notice that?

May be your NVRAM has some difficulties (is failing or will fail soon).

Bad blocks are pretty common, they get automatically managed by a badblock table.

AX86U + an unmanaged switch for more ports. I had horrible exp with AC88U. I don't use them anymore. AX88U is not much that different.

Turn off all AiProtection options. And watch it for a while. It happens again? remove devices one by one.
It happens again? Use a different AC Adapter and watch it. I think using a different adapter is better.

WAN Connection: Fail to connect with some issues - every 4 houres. Router dying or provider is too bad.

If it has no warranty you could just try to flash a firmware on it ( stock -> merlin) may be that helps but otherwise don't waste precious life time and look out for another router.
