Octoprint has stopped working. Site unreachable

MichaelBlucher · May 14, 2018, 12:28pm

Hi
My octoprint has stopped working. Site unreachable. Log file shows errors on startup.
Not sure what has upset it or when it stopped working.
Might have happened when I tried to install genealogy software gramps, which failed to install.
Perhaps that failed install upset something?
Startup Log file follows:

Please note: I have tried re-installing the main components, i.e. python etc.
Pybonjour is installed.

OutsourcedGuru · May 15, 2018, 3:44am

Not really sure. It looks like the filament plugin isn't too happy.

I take it that there are two modes for GPIO (for counting which pin is which): BCM and BOARD.

Googling that part of the error give us this. Trying to divine some wisdom from that, I think I would try to find out what version of RPi.GPIO* is loaded.

/home/knoppix/octoprint/venv/local/lib/python2.7/dist-packages/RPi.GPIO*

I might have the path slightly wrong but I'm not too far off.

PythonAteMyPerl · May 15, 2018, 9:33am

first of all... "knoppix"? Is this even installed on a raspberry pi? From memory, aren't you running this off of a live usb bootable thing on your laptop?

MichaelBlucher · May 15, 2018, 9:48am

Hi PythonAteMyPerl
Knoppix hard drive install on LapTop
Michael

MichaelBlucher · May 15, 2018, 9:57am

Hi OutsourcedGuru
The folder path is actually:
/home/knoppix/octoprint/venv/local/lib/python2.7/site-packages/RPi.GPIO-0.6.3.dist-info
Hope that helps

I highly doubt that anything relying on RPi.GPIO (including RPi.GPIO itself) will run on anything but an RPi. Try running in safe mode, if that works get rid of that plugin.

MichaelBlucher · May 15, 2018, 10:19am

Hi Gina
Safe mode?
Michael B

foosel · May 15, 2018, 10:33am

Yes, safe mode

MichaelBlucher · May 15, 2018, 10:34am

Hi Gina
I worked it out. Same result though. New log below.

I had not realized there was a safe mode.
Even in safe mode I still cant reach octoprint.
Can I remove the problematic plugin without the interface?

Based on your log, your server is running just fine and no plugin is interfering with that, so uninstalling anything won't solve your issue. That exception there looks like something is off with the pip version installed on your system, but that shouldn't prevent your server from starting and based on that log it also doesn't. Please provide the following:

the output of ifconfig on your Knoppix install
the output of netstat -tulpen on your Knoppix install
the URL at which you are trying to reach OctoPrint in your browser
a screenshot of what your browser displays you when you try to reach that URL
a screenshot of what your browser displays you when you try to reach http://<ip of your laptop>:5000 (please replace <ip of your laptop> with the IP of the laptop that your knoppix/OctoPrint install is running on)
information on how you've set this up in the first place, e.g. is there a reverse proxy in front of OctoPrint or not

Hi Gina

Back in March I had an odd problem with the pip version. Somehow that resolved itself.
I never found out how.

I've logged the output of ifconfig. It is below:

I've logged the output of netstat -tulpen. It is below:

The URL I'm using hasn't changed since march, its http://0.0.0.0:5000
I'll just give it another try now.

Its now working again! I don't get it. It wasn't working just a short while ago, now its working.

Does this sort of thing happen often? or is it just my weird knoppix setup?

foosel · May 15, 2018, 11:44am

0.0.0.0 isn't a real IP but means "listening on all available network interfaces". I'm surprised that this worked in the past - some linux distributions seem to translate it to 127.0.0.1 or something like this, so "this machine", but it's definitely not an IP you should be using when trying to connect to OctoPrint. The URL you should be using - based on your ifconfig output - is http://192.168.0.11:5000 since your laptop's wlan is bound to 192.168.0.11. If your laptop doesn't have a fixed IP address, this address will in all likelihood occasionally change though, which would also explain connection issues.

MichaelBlucher · May 15, 2018, 11:52am

Hi Gina
Where do I set the ip address for Octoprint?
Note: I've tried uninstalling octoprint_filament.
The plugin manager says it cant uninstall it.
It says its not installed, even though it still appears to be.
Michael B
P.S IP Address http://192.168.0.11:5000 appears to work. I'll use this in future.

MichaelBlucher · May 15, 2018, 12:07pm

Hi All
I have to go and feed my ferrets. I'll catch up with any replies tomorrow.
Your help has been much appreciated.
Thank you.
Michael B.

pingywon · May 15, 2018, 11:09pm

This thread was amazing! It had highs...it had lows and in the end the ferrets got fed!

MichaelBlucher · May 16, 2018, 3:31am

Hi pingywon
It not over yet. I still have an errant plugin that needs to be uninstalled.
A problem, as the uninstaller says it isn't installed.
I suspect I need to clean that up manually. Not sure how to do that yet.
And in the end the Ferrets will get fed.
Michael B.

foosel · May 16, 2018, 7:47am

I for one welcome our new ferret overlords.

MichaelBlucher · May 16, 2018, 10:03am

Hi All
This is of course way off topic. I have three Ferrets, 2 Hobs and a Jill.
Their names are (and are registered with our local Vet) as follows:
Ragnar, König der Frettchen und Polecats.
Pikachu, Prinz der Hutch, Ritter des Reiches.
Clover, Prinzessin der Hütte.
Clover is named after the clover plant. A lucky Clover has 4 leaves.
Clover the Ferret is unlucky however and only has 3 feet.
Michael B.
P.S Anyone know how to manually uninstall plugin Octoprint_Filament?
