Hello,

I’m using ncp, for a few days now, only in my LAN (local), and sometimes ncp is unavailable.

Someone knows why ncp sometimes unavailable.

how do you try to access your raspi - ip? url?
how is it connected to your network - wifi? wired?

I don’t know, you would have to get some more information, as the cause isn’t immediately obvious in the information available with ncp-info.

What happens when it becomes unavailable?
What do you see in the browser when you try to access it?

What does it say in the logs at /var/log/?
Look at ncp, apache2, mysql logs
(take a quick look in the other logs too, there might be a hint somewhere else)

Then there is sudo ncp-report & sudo journalctl -xe that you can check as well and dmesg, which are commands you run in the terminal.

dmesg might be slightly overkill and a bit overwhelmingly much info since it is more useful when troubleshooting the boot sequence or low-level system issues (system to hardware level issues) but it can be worth taking a look since we don’t know where the issue stems from on your RPi4 and there isn’t enough info to locate a cause at the moment
