I'm running pi-hole in a Proxmox container. I followed this tutorial. https://www.youtube.com/watch?v=FnFtWsZ8IP0&t=718s&ab_channel=CraftComputing In it I set custom DNS in PiHole - 127.0.0.1#5335. I have a tp-link router AC1750. After doing that I went to the router and disabled the DHCP server and then rebooted. I enabled DHCP server in pi-hole then updated gravity in pihole. I did ipconfig/all and verified that pi hole is now is m DHCP server. Everything works fine for around 1 hour then it stops working and now I do not have access to the internet and I have to go back to using the DHCP server in my router.
I tried to give the pi-hole a reserved ip but still the same issue. It runs just fine for a while then it stops. Any idea what's going on here. I also have a very long ADlist blocked using https://firebog.net/. I can not think about anything that cause this issue. Help!
