Octoprint freezes when I click either the control tab or the octolapse tab

Hello, can someone please help me figure out what is going on? Any guidance would be greatly appreciated.

What is the problem?

Octolapse freezes when I click either the control tab or the octolapse tab. So and I can't access the JPEG Streamer options to edit the camera's filters like brightness, focus, etc...It completely paralyzes me from moving any further, as I can't access anything else after it freezes. I have to click on the bowser tab just to shut down and use the instance in my network to reload the page.

What have you already tried to solve it?

I tried reinstalling, getting a new SD card, got a new PSU in case any devices were starving for more juice. The next thing I need to eliminate is getting a WiFi ex-pander to see if it's a latency issue. I've tried Angry IP scanner to see if it's connected to the network. Currently the ping is registering at 24 ms and showing the hostname as octopi.local with a port number of 80,443,8080. Also, I should mention that the little green light is not on, even though the scanner says its connected. After re-scanning, now it says it is pinging at 59 ms. Initially, the green light does come on when I power up the Rb Pi. But then, after about a minute, it stops blinking. Should I just invest in another Rb pi and replace this one. I've only had it a few months. When I first got it, I think the green light kept blinking, but I'm not sure. Should the green light always stay blinking? It's just strange that the scanner is indicating that octopi is alive when the green light doesn't blink. Is that normal?

Did you try running in safe mode?

Yes

Did running in safe mode solve the problem?

No

Can you please share the octoprint.log

3

Hi Ewald, good to hear from you. I'm new to the systems log. I thought the log I add was the systems log? Can you please guide me on how to do that?

4

The words in blue are links (like this: octoprint.log).
When you klick them, you get further information

5

Yes, of course, I appoligize for my shortcomings, I will figure it out and get back to you asap! Thank you. Please bare with me.

Also just got the record, though probably unrelated to your issue, you are still on 1.5.2 from December of last year, the latest version is 1.7.0, you really should upgrade.

Thank you Foosel,
I believe this is the correct octoprint log? Can you please confirm? I will upgrade to 1.7.0 ASAP to see if that will fix the issue.

Hi Ewald,

I think these are the correct logs. Thank you for sharing the link.

Looking through the logs, nothing seems to be amiss... Since there's a problem on the control and OctoLapse tabs, I'm enclined to think it's webcam streaming related. Could you please give us the contents of the /var/log/webcamd.log file, by connecting to your Pi using SSH?

Also, could you use the browser console (usually reachable by pressing the F12 key), and then click on one of those tabs, and make a screenshot of any error that would be shown ?

Thanks in advance

Hi SwHawk,

Here are the contents of the file. Regarding the browser console, no errors are shown. It just freezes, and I have to close the window and open a new one. Please let me know if this is the correct log. If anyone else stumbles onto this thread, please chime in if you can help. Thank you all for taking time to help me resolve the issue.

Unfortunately, the logs you've pasted here are truncated, so we can't really see what's happening. It would be easier if you could paste the output of the following command sudo tail -n 150 /var/log/webcamd.log

Also, when you paste this into your post, it would be easier to read if you enclosed the pasted contents with three backticks (```) on their own line so that the text shows as the quote below, like shown there, the code block part.

Although this line has me a bit worried, but it would be easier with the full logs.

Finally, what is the streaming URL in the settings ? Is it /webcam/?action=stream ? If so, can you open a browser and go to the following address http://octopi.local/webcam/?action=stream and tell us what you see ? Otherwise, can you open the streaming URL with your browser and tell us what is happening ?
