Your debug log shows that Pi-hole is working. It does not appear to be receiving any queries from the network.
One thing I note is that your only adlist is not in the correct format for Pi-hole, and should not be used. This is what happens when you try to import this list into Pi-hole (output from pihole -g):
[i] Target: https://easylist.to/easylist/easylist.txt
[✓] Status: Retrieval successful
[i] Received 26581 domains, 20175 domains invalid!
Sample of invalid domains:
- 2.0]
- (easylist@protonmail.com).
- &ad.vid=$~xmlhttprequest
- &advertiserid=$domain=~bee.gl|~cpashka.ru
- -ad.jpg?
Get rid of this list and use either one or both of the defaults, or any of the lists at firebog.net
As to why your Pi-hole isn't receiving DNS queries, let's take a look at what DNS a client is using:
From a client that you believe should be connected to the Pi-Hole for DNS, from the command prompt or terminal on that client (and not via ssh or Putty to the Pi), what is the output of
nslookup pi.hole
nslookup pi.hole 192.168.50.155
