Octopi server not working

[TheMcBlyat]

What is the problem?
Can get octopi.local to start then get this error message: "Looks like something went wrong during startup, the server is gone again. You should check octoprint.log"

After this connecting using octopi.local, or IP does not work. Can still see octopi on the network however and ping from CMD.

What did you already try to solve it?
Tried ethernet directly into router instead of WLAN, no difference.

Tried to access octoprint.log (not sure if I'm doing that correctly).

Logs (syslog, dmesg, ... no logs, no support)

Additional information about your network (Hardware you are trying to connect to, hardware you are trying to connect from, router, access point, used operating systems, ...)

Using Raspberry Pi B rev 1.0 (issue here?)
Tried connecting from Win 10 PC (wired), Samsung S10, iPhone 6s (Bonjour?)

Hi @TheMcBlyat ,
I notice you say you tried to access the octoprint.log, but haven't posted them here. They can be found in ~/.octoprint/logs if you can't get into the server. Octoprint.log <- click this link to find out where to find them if you get stuck.

To help with issues like this, we really, really, really need the log, as it will more than likely explain the issue. Can you also try starting in safe mode < click the link to find out how

Hi @Charlie_Powell,
Have now got the log file, sorry for not posting it first. This was running in safe mode:

I am running the last version of octoprint (0.16.0) to see if it would help. Spoiler; it didn't. Same issue as 0.17.0

@TheMcBlyat

I am running the last version of octoprint (0.16.0) to see if it would help. Spoiler; it didn't. Same issue as 0.17.0

The recent version of OctoPrint 1.4.2 - referring your log, you are running 1.3.10.
0.16.0 is a former version of OctoPi - recent one is 0.17.0

[Charlie_Powell]

No issues seen in the logs, so the server think's its alright. Try updating OctoPrint, 1.3.10 is quite ancient now, getting on for 2 years old.

What is the difference between OctoPrint and OctoPi? Are they the same thing?

No, OctoPrint and OctoPi are not the same thing. OctoPrint is a fully featured print server/web interface for 3D printers, written in Python and HTML/JS. It is platform agnostic and runs basically everywhere where you can install Python (the full version, not Micropython), be it a cheap single PCB computer like the Raspberry Pi running Linux, a fully featured gaming PC running Windows, a Mac running MacOSX or a server running some BSD flavor. It was created and is actively maintained by Gina Hä…

[TheMcBlyat]

Sorry, yes I mean't last version of Octopi. I'll try updating Octoprint and see what happens.

[TheMcBlyat]

Updated to 1.4.2, still the same. Could it simply be the Pi is too old? B Rev 1.0?

[TheMcBlyat]

I've updated to latest Octoprint but still no luck? Same issue.

[Charlie_Powell]

Can you try in safe mode? And exactly what message do you get? Not sure I've seen this one, maybe it comes from the intermediary server, before the main OctoPrint has started up.

[TheMcBlyat]

This is the message I get when connecting: " Looks like something went wrong during startup, the server is gone again. You should check octoprint.log ."

Try a reinstall?
SSH into the Pi and run:
~/oprint/bin/pip install --force-reinstall --no-cache-dir octoprint
If that does not work, try getting a new image of OctoPi and flashing it, maybe?

Seeing as there is no error, it could simply be that something has got corrupted? Worth a try, maybe? not sure what else.

No difference after trying both. Maybe the Pi is just too old? Or a network issue?

Maybe the Pi is just too old?

Raspberry Pi Model B Rev 1

Not old, but quite underpowered.

After a few reboots, I'm now getting this message, " OctoPrint server started, waiting for it to get ready..." Hasn't moved off this screen. Surely down to the lack of performance from that single core?
