Plugin messes up my camera stream

[Natelicious]

Initially before a print

• Camera stream works in Octoprint, I can see the video in the control tab.
• In the telegram bot, everything works well. I can see the image using /status.

After initiating a print using Octoprint

• Telegram cant take a picture and I get "ERR GET IMAGE"
• My video stream in Octoprint Control tab states "Webcam stream loading..." forever.
• In the settings, "/webcam/?action=stream doesn't display" anything
• In the settings, "http://127.0.0.1:8080/?action=snapshot doesn't display" anything
• When I reboot my Raspberry Pi, I still cant see any image/videos from Octoprint and Telegram.

Octoprint version: 1.7.2
Octopi: 0.18
Camera: Raspi Cam (Did not edit any settings in putty)
Pi: Raspberry Pi 3b+
Printer: Ender 3V2
Firmware: Jyers 1.35b

Is there any solution out there, hope someone can advise me. I've reflashed OctoPi and tried again but the same result still happened. Thank you!

Hi

did you tried a print with telegram disabled and that create no problem?
you said the reboot didn't fix the problem? so how do you fix the problem?

could you send a logfile of a print with telegram plugin activate?

thanks

I had the same problem after upgrading plugin to the version with implemented socks5 proxy.

Some time ago before upgrade i manually merge this PR with proxy support to local version of plugin, so proxy urls was already configured in my config.

After upgrade bot stopped to send images from the webcam with [ERR GET IMAGE] error, however camera and snapshots in octoprint works fine.

I tried to figure out the problem, enabled debug logs and saw:

I had checked my proxy logs:

2021/11/16 09:05:14 [ERR] socks: Failed to handle request: Connect to 127.0.0.1:8080 failed: dial tcp 127.0.0.1:8080: getsockopt: connection refused
2021/11/16 09:05:14 [ERR] socks: Failed to handle request: Connect to ::1:5000 failed: dial tcp [::1]:5000: connect: cannot assign requested address

It seems that plugin tried to get image through proxy instead of direct connection to localhost.

In conclusion, i have disabled proxy in plugin settings and i was able to see image in bot response message.

@giloser I've managed to get it to work!

However I followed the same steps that I took for setting up the plugin the last 3 times. I am unsure of how it worked this time round. Thank you all for your help anyway. Stay safe and great plugin btw, personally I feel better than the octoslack.
