Dashboard shows only localhost, some clients dont work

[ydpihole]

Setup:
I have a raspberry pi zero w that I have setup with raspbian lite, this is running with a static ip address of 192.168.2.10.
Have a Asus router that is configured to hand out 192.168.2.10 as the DNS server. The option to advertise the router as a additional DNS server is set to false.
I see clients getting the pi hole's ip address as the DNS Server.
Example output from ipconfig /all on a windows machine:

Wireless LAN adapter Wi-Fi:

Expected Behaviour:

Clients andriod, windows laptops are able to resolve dns queries and their corresponding data shows up on the admin dashboard.

Actual Behaviour:

1. On the Dashboard I see only localhost.
2. Some clients are failing to resolve names.
   Example of a nslookup from the same windows laptop form which I had pasted the ipconfig output.

C:\Users\user1>nslookup google.com 8.8.8.8
Server: dns.google
Address: 8.8.8.8

This windows laptop does show Internet is not connected even though I explicitly whitelisted www.msftncsi.com and msftncsi.com .
Similarly a moto andriod phone doesnt shows connectivity failed but when I ask it to continue to be connected and turn off mobile data, things still work on the andriod device.

A Xiaomi MIUI device continues to work as though nothing is wrong. But even this device doesnt show up on the admin panel which leads me to a suspicion that its using a diff DNS Server. Note, I the private dns functionality in MIUI is off.

Would appreciate any pointers to figure out whats happening here.
Have restarted the pi hole, flushed network table, restarted dns resolver, flushed logs. All of these did not help.

This is what the dashboard shows

You configured Pi-hole to listen on eth0 but this interface is not present/configured. It seems that your device is connected by wifi (wlan0). Run pihole -r and choose reconfigure

Thanks, this was it.
Had messed up the static ip configuration. I did it outside the pi hole setup.
By this time I had format the sd card.
But for future reference for folks who might stumble upon this.
Just let the pihole setup script guide you through setting up the static ip.
