Expected Behaviour:
I should be able to log into the pi-hole web interface.
Actual Behaviour:
Whenever I try to reach the Pi-Hole server, I get a connection timed out error in my browser.
Debug Token:
qkcjv7xl67
I've tried reaching it by direct ip, by http://pi.hole/admin, and by my custom dns at http://pihole.noreallyitis.me/admin. No matter how I try accessing it or whether or not I reboot, I just get connection timed out.
It is being hosted on an AWS t2.micro server with a completely open security group running Ubuntu 16.04
The pi-hole is configured with an IP in the 172.x.x.x range, but the domain name you listed is for an address in the 18.x.x.x range. The URL you provided opens the admin page for me here.
Yes, I was running wide-open just to double check it wasn't a weird AWS security group issue. It's working okay now, but only if I try by direct IP or my updated DNS record. However, I think the Pi-Hole has the original, non-elastic IP cached as the correct entry for resolving pi.hole. How can I clear the DNS cache on the Pi-Hole so that it can update that?
