My first home server would get lost on the network every week, at different times and without any apparent reason. I performed hard resets by unplugging and plugging it back in.

After several months, I decided to connect a screen to it, and I initially thought it had hung up, but it hadn’t. After some investigation, I discovered that every time my router obtained a new dynamic IP address, the server lost its network connection, requiring a reset. I wrote a script to check the network connection every minute, and if it’s lost again, it will be reset.
