PiHole stops responding, even with new SD card

Help

Hello Pi-hole discourse!

Expected Behaviour:

I am using a Raspberry Pi 3 Model B Rev 1.2 with Raspbian 10 (buster). Being able to use it for long periods of time without having to reboot

Actual Behaviour:

Been using this setup for half a year, everything perfect. Then, a couple of weeks ago the raspberry would suddenly become unpingable and my whole network would be unasble (because I use the DNS as well as the DHCP server). I tried manually assigning myself an ip and I still couldnt ping the raspberry. A simple reboot would fix it and everything would be perfect for a week or so. Then the time would become shorter. Last week a reboot would make the pi usable for 5 minutes tops. Thats when I bought a high endurance sd card. Installed everything from scratch as to not have some software bug leftover. It worked nicely for a day and then the same issue appeared. I had to restart.
I doubt its the power supply as I get no errors regarding power delivery like you do when the power supply is sketchy. It was also working great for months on end.

Debug Token:

Thank you for the help!

This has all the appearance of a failure on the host device.

Any way to check on that?

You can look in the system logs for any errors, as a start.

/var/log/syslog

However, your best resource may be a Pi forum or forum for your OS to troubleshoot issues at the OS level.

To be honest, there doesent look to be anything wrong in the syslogs
