Web interface not available

UncleCCC · January 24, 2020, 9:53pm

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?

pi@raspberrypi:~ $ sudo service octoprint start

What kind of printer is it?

UncleCCC · January 25, 2020, 8:29am

Good morning,
This is my first printer, so I bought a small one 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?

UncleCCC · January 26, 2020, 8:43am

Can Ocotprint be started even if no printer is connected?

UncleCCC · January 27, 2020, 12:58pm

Nobody has any ideas?

Ewald_Ikemann · January 27, 2020, 1:13pm

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

foosel · January 27, 2020, 1:18pm

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

UncleCCC · January 27, 2020, 1:49pm

@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.
