I'm using a Raspberry Pi 4 B 2GB and I install pihole with docker with Portainer. I install WireGuard too. I'm trying to connect by browser with the ip+port. My fix ip is 192.168.0.10
Actual Behaviour:
I can't connect with 192.168.0.10:5353 o 192.168.0.10:5353/admin But if I use 192.168.0.10/admin, I connect. This makes a problem because pihole is not running in Portainer. I'm not an expert but I think I installet to use by the 5353 port and it's not connecting.
Pi-hole is a DNS server and it is expected to use port 53.
The good news is: your Pi-hole is already using this port for DNS:
[✓] tcp:0.0.0.0:53 is in use by pihole-FTL
This is not a web page, so you can't connect to this port using your browser.
You will need to configure your router (or each device individually) to use Pi-hole as DNS server.
The DNS IP is 192.168.0.10
Part 2 - Web server:
The web interface runs in a web server called lighhtpd.
This web server uses a different port (usually 80).
You are already using this port too:
