Something is powering off my Truenas

phier · August 31, 2025, 8:13pm

hello,
i just physically moved my truenas from one room to another, what is happening now is that once it boot on, after few minutes/3-5 it goes down… i got message into the terminal see below.

I am desperate, what happened? thanks for advice, or investigation.

root@truenas[~]#
*** FINAL System shutdown message from root@truenas.local ***

System going down IMMEDIATELY

i was login via web ui using chrome.

i found that post : SOLVED - Immediate shutdown after root login in GUI | TrueNAS Community

tried to login via Firefox ; for now no reboot.

so chrome is somehow rebooting it? isnt that weird?

thanks

The explanation is in the linked thread, did you try the proposed solution?

phier · August 31, 2025, 10:26pm

@neofusion
thanks for the response.

I skipped Chrome, and Logged-in via Firefox - and it works fine now; ie no reboot.

Is it possible from the provided logs identify/say that all these reboots were executed “somehow without my intervention” from chrome?

thanks!

It would be evident in the browsing history of Chrome.
