Web interface not available

What is the problem?
I have installed Ocotprint on my Raspberry following these instructions Link
If I start the process: ~/Octo/venv/bin/octoprint serve the web interface is accessible under ip:5000.
I start the service: sudo service octoprint restart
If the web interface is not accessible under ip:5000.
But according to the status the service is running. Does anyone have an idea what the error is?

What kind of printer is it?

Good morning,
This is my first printer, so I bought a small one :slight_smile: MONOPRICE SELECT MINI V2
When I start the process, everything works, only the USB port is not recognized automatically, I have to select it manually. Is that the cause?

Can Ocotprint be started even if no printer is connected?

Nobody has any ideas? :frowning:

What browser do you use?
Are scripts enabled?
Are cookies enabled?

Yes it can.

It is generally strongly recommended to use the provided OctoPi image to avoid issues like this. It's almost impossible to tell you what is going on here since we don't know if you might have accidentally skipped or not correctly followed a step in the tutorial.

But I'd suggest to

  • check that ps -ef | grep -i octoprint actually shows the process as running
  • check that netstat -tulpen shows the port as being listened on
  • check that tail -f ~/.octoprint/logs/octoprint.log logs regular heartbeat messages every ~10min
  • verify that the paths in your initscript are configured correctly for your virtual environment

@Ewald_Ikemann
All browsers...
As I said, I start Octoprint in the console
~/Octo/venv/bin/octoprint
It works, reach the web interface and everything works
As soon as I close the console the server stops, that's normal.
So it can't be the browser

@foosel
I understand that, but on the Raspberry many applications run e.g. Homematic, PiHole, Deconz etc.
If it doesn't work out then I buy my own Raspi for Ocotorpint.

The 5000 port does not seem to be open?

I think it's best I get a Raspy for Ocotprint

Yeah, that is definitely not recommended. Driving a 3d print job is quite some work, you want to dedicate a Pi to that, not have it fight for resources with other stuff.

Also I agree, it looks like stuff ain't running at all.

Additionally, PiHole will (quietly) block OctoPrint's attempts to update things.
