Can't connect to second OctoPrint on same RasPi?

Get Help Networking
1

So I'm trying to set up two instances Octoprint for my teacher and so far I've got the first instance up and working, but the second one I can't seem to connect to. The service SEEMS to be working, but when I try to connect to it, it refuses to connect.

Its running on a RasPi 3+ (I think), and its wire connected to its own router that the computer is connect to via WiFi. The computer I'm using to connect to OctoPrint is a iMac. If anyone can give me some suggestions to run tomorrow when I go back that would be very helpful.

Hi :slight_smile:
Well I think it would be the easiest if you tell us what you have done so far and how you configured the second octoprint instance.

Edit: also I found this guide quite helpful. Maybe it helps you too.

This is the guide that I used. I basically tried to follow this guide and I thought I did everything correctly. I do have it connected to two different routers so now I'm thinking I might have to change some settings one both of them.

This is what I got. If I try to go through this port (192.168.x.x:5001 or 5000) it refuses to connect.
