Yes, I'm running CentOS 8 but I didn't install Admin Console because I don't want to use it.
Pi-hole host is a VPS server, gateway was a public IP - I was following instruction and checked it twice. How it should be set?
EDIT:
I reconfigured Pi hole - now it has one internal address 192.168.5.1 but it still doesn't work.
It says:
*** [ DIAGNOSING ]: Networking
[✓] IPv4 address(es) bound to the wg0 interface:
192.168.5.1/24 does not match the IP found in /etc/pihole/setupVars.conf (Use IPv6 ULA addresses for Pi-hole)
[✗] No IPv6 address(es) found on the wg0 interface.
[i] Default IPv4 gateway: 51.38.124.1
- Pinging 51.38.124.1...
ping: sendmsg: Required key not available
[✗] Gateway did not respond.
And
[root@vps817653 ~]# cat /etc/pihole/setupVars.conf
BLOCKING_ENABLED=true
PIHOLE_INTERFACE=wg0
IPV4_ADDRESS=0.0.0.0
IPV6_ADDRESS=

PIHOLE_DNS_2=1.0.0.1
QUERY_LOGGING=true
INSTALL_WEB_SERVER=false
INSTALL_WEB_INTERFACE=false
LIGHTTPD_ENABLED=false
It says that gateway is not reachable while:
root@vps817653 ~]# ping 51.38.124.1

What's wrong?
