Thank you for the response. I ran pihole -g -r and still have the same results. If I add a custom client I get a message saying it was successfully created, but never shows in the client list. Just says "Loading..."
My issue was totally different from yours. Well, we had the same issue, different cause. I had a customized theme on my older PiHole installation and it was causing issues with the update.
[✓] IPv4 address(es) bound to the tun0 interface:
10.8.0.1/24 does not match the IP found in /etc/pihole/setupVars.conf
based on that make sure the interface and IP are correct this can be accomplished with pihole-r and selecting reconfigure be aware this basically will reset things back to fresh
Thanks for the suggestion. Ran pihole-r and reconfigured, now shows eth0 vice tun0. Still doesn’t show anything in clients or network, but clients are actively using pihole and all expected ads are being blocked.
Unfortunately I am unable to use Pi-hole as my DHCP server until I can get the groups working. I will try a clean install on another card and see if it works that way.
