i can’t get into umbrel via ssh.how can i restart it
Hey there! 
What about ssh umbrel@YourNodeIP does that work? Are you able to detect the node on your network with something like Angry IP Scanner to find its IP? https://angryip.org/
If none of the above options work, and you can’t SSH in or reach your dashboard, you can unplug the device. I would recommend making sure you have your backup/seed phrase in order just in case, this is only if we can’t safely power down any other way.
Re-flashing the Umbrel OS onto your SD card also helps with a lot of issues, and helps our chances getting back into your dashboard successfully.
If the above doesn’t work feel free to give us some more details so we may continue assist:
- On what device / OS you are running Umbrel (Raspberry Pi, Ubuntu Desktop/Laptop)
- How is your Umbrel connected to the Internet (Ethernet, WiFi)
- What type of drive you are using (HDD, SSD)
- Any recent changes you made, or anything else you think can be relevant…
