So I assume you have installed DAppNonde on a machine on your own, if you are not able to connect to your DAppNode anymore there are two different ways you can reach back your DAppNode:
- Plug a monitor and a keyboar and mouse to your machine
- Connect via ssh, if you do not know how to do that follow this guide
Once you reach your DAppNode, I recommend you to update your DAppNode to the latest version and reboot, to do that you just need to paste a command in the terminal, the documentation to do that can be found here:
wget -qO - https://installer.dappnode.io | sudo UPDATE=true bash
