When I tried pihole -g I've also got an error..

pihole -g
[✗] DNS resolution is currently unavailable

Here's my /etc/resolv.conf:

nameserver 1.1.1.1
nameserver 1.0.0.1

I believe it has something to do with the gateway, the old one ends with .254 and the new one ends with .1, but I was still not able to get it running.

Here's my log, since I can't upload it coz.. DNS

From your debug log:

[i] Default IPv4 gateway: 192.168.1.254
   * Pinging 192.168.1.254...
[✗] Gateway did not respond. (https://discourse.pi-hole.net/t/why-is-a-default-gateway-important-for-pi-hole/3546)

Edit file /etc/dhcpcd.conf and look for an entry similar to this. Edit the static router to the correct address. Then reboot the Pi with sudo reboot now

interface eth0
    static ip_address=192.168.0.155/24
    static routers=192.168.0.1
    static domain_name_servers=127.0.0.1
