Can't open Octoprint using IP in browser

I'm fairly new to all of this but I have flashed an old model B with Octoprint and connected it to my home network and printer, and I can see it on my router. When I paste the IP address into my browser I get a 404 error. Any ideas?

What IP address are you using, the IPv4 or the IPv6 type?

And did you add the port number?

I'd try using SSH to connect to the RPi. If that works, it allows a larger number of troubleshooting options.

My guess is that he'/she's been issued an IPv6 IP address and they're trying to use that in their browser without surrounding it by square brackets.

IPV6 is the devil's work !

The devil's work I say !

Seriously. Connect keyboard mouse and monitor to pi

type sudo raspi-config

Select networking

then select normal ip goodness




Profit !


maybe if you are not conected to the same network like your raspberry, on the computer were you tipe the ip adress , you can"t acces it
