Sleepy

I seem to be having the same problem as Andiroo2 after the most recent update (as of 12/10/2021). Logs didn't show any issues. I have mine set to auto-start through the UnRAID container GUI. I tired accessing the server using a browser and tried using the reboot function in the GUI, and nothing started up for me. However, after using the stop and start buttons, it worked.

I tried the cheap and fast way and it worked out... I copied/backed up my current 6.5.3 USB drive. I reformatted and created a 6.6.6 USB drive. I then copied over my config folder, and it booted up with no trouble.

I am currently having the same problem but possibly different issues. ( I still need to check some things from this post. thank you for the tips/heads up!) I have a paid pro license. I tried jumping the shark upgrading from 6.5.3 to 6.6.6. My server would not reboot or shutdown after installing the update through the GUI. I kept getting a 504 Gateway error through the on multiple browsers, and multiple computers. When I tried refreshing the page, it would just cough back up to the main page as if I didn't ask it to reboot or shutdown. I tried asking nicely to reboot and shutdown through the GUI, asking in a bit more stern voice through the terminal, and then yelling at it while holding the power button. When I got it to hard reboot, I hooked a monitor to it see what the heck was going on. After going through the BIOS bit all I get is a half a blinking cursor. No boot sequence, no indication that the USB drive was unbootable... nothing. I yanked the USB after shutting down the sever again to see if there were "files." Things seemed to be in order, but I didn't get much time to start pulling log files yet. My next thing I'm going to try... Make sure m BIOS is up to date. Copy over my config files from by current USB. Grab another USB and install 6.6.6 on that in trial mode to see if it boots up try taking my current USB, copy over 6.6.6 and copy over my config files and see if that boots up. If that doesn't work or if I have some cycles in-between I'll try to take a look at the logs.
