Hello,

You may want/need to update your Anki and/or your add-ons

The most recent version of Anki can be downloaded from the Anki website (https://apps.ankiweb.net/) and add-ons can be updated by going to Tools - Add-ons - Check for Updates within Anki.

Give that a shot and let me know if it helps. :slight_smile:

I had the most up-to-date version and had the same problem and was advised to download the older version and was still dealing with the same problem

@abdo.nh tried these below. Still didn’t work, can you investigate further?

This is a known issue with some macOS users.

Please try the following:

  1. Check your proxy settings: How do I fix this error! - #10 by cikedi2 1
  2. Try downgrading to Anki 23.12.1

Can you try with a different network if available?

This error will probably be fixed in a future Anki version soon.
