Worked for half a year. During this time, several firmwares have changed, which I regularly installed. The first problems appeared in the summer - because of the heat, it hung on access, but regularly performed the assigned tasks. And now a new attack. I noticed that the system memory is loaded at 100%. Attempts to connect to clarify the details ran into a problem - all known logins were declared invalid. Although only a couple of weeks ago another new firmware was installed describing that problems with access to management were fixed. After a forced reboot, it stopped serving ports and turned into a useless piece of metal.
