Connection Status: Not Connected to Canvas There seems to be an issue

Updated to the latest version of canvas on octoprint and it can’t connect and gives the above error

When I look at the mosaic log I see this:

Hey @studiot, thanks for reaching out. Have you gone through the steps here to link your Canvas account via an activation code?

@alina I have tried that. I don’t have the screen in step 2. I have the attached photo.

Hey Ryan, could you attach a screenshot of what you see under the software update tab in OctoPrint? This should show that Palette and Canvas plugins are both at version 3.0.0

Thanks for sending that over Ryan, could you please send us your mosaic.log and octoprint.log from a day that this issue occurred? You can use the steps here to do so (mm3d.co/octoprint-logs). The mosaic logs are in the same place as the OctoPrint logs. If you have trouble attaching it here, please send it over to support@mosaicmfg.com

@alina It won’t let me attach a file to this. Rather than paste all the data in I will email you.

I am having the exact same issue. I shut my Hub and printers off before going out of town and when I returned it gives the same message as above and I am no longer able to get a code to add it back to my Canvas setup.


I tried uninstalling and cleaning up the plugin data but nothing helps. There is no way to log out of my canvas account on the hub. This is a major issue and not an isolated incident. Let me know if there is anything you need from me to help.

Mosaic have my log from Octoprint. Perhaps you could send them the log with as detailed in the instructions above and put the discussion topic in the title. @Alina Would this be helpful?

Hey @studiot and @opy01, thanks for your patience with this - we are actively looking into this issue and I will update this thread as soon as possible. @opy01 If you could send me a mosaic and octoprint log to alina@mosaicmfg.com, that would be great as well.

@alina sorry for the delay. The logs have been sent.

Hi everyone, thank you for your patience with this. The Canvas team has looked into this and will be releasing a new plugin version on Wednesday July 19th to address this issue. I will update this thread with the new links then. Please let us know if you continue to see this issue after installing the new versions.
