**Environment:**

OS = DietPi v6.31.2  
Pi-Hole Version = 5.1.1

**Error:**

I have been running Pi-hole for the past month, and as of yesterday, I have a problem.

From the command line, I did a pihole -g and get the error “DNS resolution is currently unavailable”

**Troubleshooting:**

After searching on the forums, it looks like it has to do with /etc/resolv.conf

There’s a SINGLE line that says nameserver 192.168.1.1 (which references my router).

I know if I change it to 127.0.0.1 and save it works fine.

**Help Needed:**

The problem is when I REBOOT, the nameserver reverts BACK to 192.168.1.1. How do I fix this so it always stays to 127.0.0.1 ? This used to work FINE until yesterday. Unsure as to what changed…

**Additional Note:** I reached out to Pi-Hole’s support FIRST and they recommended I direct my inquiry over here.

Thank you for any help, it is greatly appreciated!

Hi,

I guess you opened same issue at Github? correct? If yes, pls let’s stay at one place. It doesn’t make sense to open it twice
