This error is on AnkiHub’s side, not your Anki installation.

What’s happening:

  • The AnkiHub add-on is trying to upload logs to AnkiHub.
  • AnkiHub’s server is responding with 500 Internal Server Error, which triggers the traceback you see.
  • That HTML (<!DOCTYPE html>...Server Error) is the error page from AnkiHub, not from your computer.

What you can do right now

  1. Confirm you’re logged in correctly

    • In Anki, go to Tools → Add-ons → AnkiHub → Config / Settings (or AnkiHub menu if you see it).
    • Log out of AnkiHub, then log back in with your AnkiHub account.
    • Restart Anki and see if the error still appears.

  2. Temporarily disable automatic log upload

    • In the AnkiHub add-on settings, look for anything like:
      • “Send error reports automatically”
      • “Upload logs automatically”
    • Turn that off if it’s enabled.
    • Restart Anki and check if the pop-up still appears when opening/syncing.

  3. Update the AnkiHub add-on

    • Go to Tools → Add-ons → Check for Updates.
    • Make sure the AnkiHub add-on is on the latest version.
    • Restart Anki and test again.

  4. If it keeps happening

    • This is most likely a temporary server issue on AnkiHub’s side (since it’s a 500 error).
    • Please reply in your topic with:
      • Whether the error happens:
        • every time you open Anki,
        • every time you sync,
        • or only when you click “Send logs” / “Report error”.
    • Also let us know if:
      • You can still sync your AnkiWeb account normally (Anki menu → Sync).
      • You can log into https://app.ankihub.net in your browser.

If you share that extra info, we can confirm whether it’s just the log-upload feature failing or if something broader is affected, and we can escalate it to the AnkiHub team if needed.
