Octoprint service is not running

lberstein · February 26, 2023, 3:51pm

What is the problem?

After running octoprint sucessfully for several months, now it´s suddenly not starting up and showing the "Octorpint server is currently not running message"

What did you already try to solve it?

Followed the suggestions on that same page (I´m not getting anything from the commands to check the server is running), also tried a force reinstall, and a few other suggestions I found in the forum that I don´t remember. I haven´t changed the pi username.

Have you tried running in safe mode?

Yes, but I can´t. When I try any octoprint commands from terminal its says it doesn´t recognize the command. Editing the config.yaml file yielded no change in behaviour.

Did running in safe mode solve the problem?

No

Systeminfo Bundle

OctoPrint version : 1.8.6
OctoPi version : 0.18.0

Not sure if this is the info required?

I tried pulling the log file, but doesn´t really help me:

I assume "ERROR - Uncaught exception" is bad, but doesn´t give me much to work with

I'm running in the same issue now... Octoprint was fine until my print of 4 days finished last night and now suddenly it refuses to start the octoprint servive, even when I add the Safe mode option to config.yaml... anybody who was able to get it back to life or at least extract plugins and data from plugins from it so I can reinstall it on another sd card?

PrintedWeezl · April 4, 2023, 7:13am

We need a systeminfo bundle

FGOD · April 4, 2023, 7:36am

I would love to do so, but is there a terminal way to do this because it is kinda hard to get that from the web interface if octoprint is not starting...

PrintedWeezl · April 4, 2023, 7:39am

yup
ssh into the pi and run ~/oprint/bin/octoprint systeminfo . (the dot is important)
then you can download it with WinSCP.

FGOD · April 4, 2023, 7:42am

Thx but that seems to quit with a message:

sentry is attempting to send 1 pending error message
Waiting up to 2 seconds
Press ctrl-c to quit

And then it returns to the prompt

FGOD · April 4, 2023, 8:16am

do you have the specifics of what is needed in this case? because maybe I can give or generate the info in another way...

in any case, I'm running octoprint 1.8.7 and octopi 0.18.0 on a pi3 B

after seeing this and rethinking I started looking at the users.yaml file and that was empty somehow (probably not normal)...

There was also a users.v1.yaml file in the .octoprint folder and after copying that one to users.yaml it was able to boot up again.

No idea though why my users.yaml was copied to users.v1.yaml and how I ended up with an empty users.yaml file while the pi just shut down as normal after the print was finished...

glad you found a solution
now that OctoPrint works again - could you do me a favor and upload a systeminfo bundle so we can try to figure out what happened?

FGOD · April 5, 2023, 5:08am

octoprint-systeminfo-20230405060550.zip (152.4 KB)

Right, totally forgot about that here you go!

I do suspect that in my case, somehow part of the sd card got corrupted because the octoscreen instance kinda failed too and I needed to do a file system check to get everything fixed on octoscreen too, but what the cause of the corruption was, no idea so far... but I'm glad it happened after the print was done (4 days and 8 hours print )
