Hello,

Are you experiencing this error repeatedly? Try logging out of AnkiHub then logging in again to see if the error goes away.

Hi there,

The error happens every time I open the Anki app. I have tried to restart my computer, though the error persists. When the error message pops up, I can’t utilize any functions of the Anki app because the application stops responding, requiring me to force quit.

Is there a way to log out of AnkiHub without the Anki app? As mentioned, I cannot perform any functions or access the Anki toolbar in the app because the error message freezes the app.

Thank you!

I asked a developer to take a look at it. In the meantime, you can safely delete the add-on and re-download it. This will cause the add-on to request your credentials again, and once you log in, everything should work fine.

Since you cannot perform any actions because of the error, you should start Anki in Safe Mode..

  • Starting Anki in safe mode will temporarily disable all add-ons. To do this, open Anki while holding down the Shift key.
  • Go to Tools > Add-ons. Select the AnkiHub Add-on and delete it.
  • Close Anki, then open it normally. Go to Tools > Add-ons, get add-ons, and put this code: 1322529746
