Thanks for the screenshot—that helps.

That message is coming from the AnkiHub add‑on when it tries to connect to the AnkiHub servers and fails. A few things to check:

1. Check internet / VPN / firewall

   • Make sure your internet is working in a browser.
   • If you use a VPN, ad‑blocker, or firewall (Little Snitch, corporate network, university Wi‑Fi, etc.), try:
     • Temporarily disabling it, or
     • Switching to a different network / hotspot.
   • Some networks block AnkiHub’s API domain, which can cause this exact kind of error.

2. Check AnkiHub add‑on status

   • In Anki, go to Tools → Add-ons and confirm AnkiHub is enabled.
   • Click Config on AnkiHub and make sure your email is correct.
   • Try restarting Anki afterwards.

3. Update Anki + AnkiHub

   • Make sure you’re on a supported Anki version (per AnkiHub docs).
   • In Tools → Add-ons → Check for Updates, update AnkiHub if an update is available, then restart Anki.

4. Try to reproduce and note when it appears

   • Does it happen when:
     • Opening Anki?
     • Clicking the AnkiHub button?
     • Syncing a particular deck?
   • That detail will help narrow it down.

5. If it still happens, please add:

   • Your device + OS (e.g. macOS 14, Windows 11).
   • Your Anki version (from Help → About).
   • Your AnkiHub add‑on version (from Tools → Add-ons → AnkiHub).
   • Whether you’re on a school / work network or a home network.

Post those details (and any new screenshots) in your topic and we can help you further troubleshoot, or escalate it to the AnkiHub team if it looks like a server‑side issue.

Hello,

I would be happy to help.

The message in question is from Anki, rather than AnkiHub. In most cases, as indicated by the message itself, the issue lies with your local network

You might try switching networks, or double-checking any VPN’s or firewalls or similar

For further assistance with Anki and network errors you might also try reaching out on the official Anki forums: A network error occurred. Error details: ⁨error sending request for url (): error trying to connect: tcp connect error: Connection refused (os error 61)⁩ - Syncing & AnkiWeb - Anki Forums

Thank you Brian. I switched to using my hotspot and it worked! However, I tried that before submitting a request, and it did not work then
