I installed octoprint on my Pi 3B today running raspbian. I followed the guide about installing octoprint on raspbian this guide. Everything went good without any errors and the server can be started just fine.
If i go to http://0.0.0.0:5000/ (which is what the guide says) on chromium on the pi itself i can acces the interface just fine. But if i try this on any other pc it can't reach it.
I have already tried every other adress like octopi.local and the local ip of the pi on both the pi itself and other pc's but that doesn't work either. I tried installing HAProxy which is also in the guide. It installed fine and i did everything in the guide but it doens't change anything.
yesterday i tried just flashing an sd card with the octopi image and i got to acces it just fine on my pc. So it's probably nothing on the pc or router end i presume.
I'm running the latest version of everything.
