[Pi-hole should be accessible]
_[I have a Pi 3 B running Raspian Buster, in which I installed Pi-hole. It keeps locking up after a few hours to a day and becomes unresponsive, no display or ssh access. The only way to remedy is to power cycle the unit. This is happening on 2 separate Pi 3 B’s. Any help would be appreciated.
Here are the details:
OS: Buster - Full
SD Card: 16GB Micro SD HC
It is connected via Ethernet
I have connected a keyboard/mouse/monitor and the Pi does not respond or display anything. This is the case for both of my Pi 3’s. This only occurs when I have my router using them as the DNS server. If they are not providing any DNS filtering then they run forever without issue. The only way to get them working again when they lock up is to powercycle them. They still work, per say, when it locks up, but no gui is accessible to try and remedy the situation.]_
_[I took a log using journalctl -f to see what happens when the gui becomes unresponsive and have included it, or at least a section, as it generated a 2.5gb log over 2 days.
