TS-251 unable to shutdown or reboot the NAS

This morning, I’m experiencing strange behavior. When I log into the QTS interface, I always get a screen with a window waiting for a process to shut down (see attached image). I force the shutdown by clicking “Shut down now,” pressing the power button for 5 seconds, or unplugging the power supply. After restarting, I see this same window again when I log into QTS.

Has anyone on the forum encountered this before?

There was no picture attached

Does the issue still exist?

If so, please remember to include an image or screenshot when you reply. Thanks!
