Hello. For about a week, I can’t sync my collection. I constantly get the error “error send request for url ()”. My internet connection is stable, the browser and all other services work fine. I tried disabling the antivirus and reinstalling Anki. After reinstalling, I got another error when trying to download add-ons/update: “failed to run (2): … caused by: an existing connection was forcibly closed by the remote host (os error 10054)”. I managed to solve this specific error by disabling the cache and enabling mirror downloads, but the main sync issue remains. What I’ve tried: · Disabled antivirus (Windows 11 Defender). · Reinstalled Anki completely · Changed DNS to 1.1.1.1 and 8.8.8.8. · Tried using a VPN. My main constraint: I have unsynced progress on my Android phone that I don’t want to lose by forcing an upload from the PC. I’ve been using Anki for 2 years and would be very grateful for any help. Thank you. ---

You can export your collection in AnkiDroid and import it to your PC. ---

When you sync your phone, then log in on your computer via your internet browser, does that work for you? In other words: Is it only the anki binary that has issues connecting to ankiweb or your entire Windows OS? ---

If I export a collection from AnkiDroid, I will lose the words that I added when I couldn’t sync. ☹ ---

Only with Anki on Windows. The sync on the phone is fine ---

You can export any notes that haven’t been synced with scheduling information and import them back after syncing. ---

So that would be exporting an Anki deck package, not the entire collection? In that case, I understand, but it doesn’t solve my sync problem. I’ll keep it in mind as a backup option ---

Yes. It sounded like you can upload from your PC so maybe that will fix it? ---

Those sorts of errors are usually coming from your internet connection or your device. You mentioned a few things, but you should check everything – VPN, proxy, antivirus, firewall [see: [Error establishing a secure connection when syncing - Anki FAQs](https://faqs.ankiweb.net/error-establishing-a-secure-connection-when-syncing.html)]. If you can connect your computer to another internet connection, like a hotspot, you might be able to work out whether it’s your internet connection or something on your Windows machine. > [@Kate228](#): > > My main constraint: I have unsynced progress on my Android phone that I don’t want to lose by forcing an upload from the PC. Do you _also_ have unsynced progress on your PC? A one-way sync in the other direction is also an option. But none of that matters until you get sync working again! For now, an APKG export/import is annoying, but it will work to move your updated collection from device to device. [AnkiDroid User Manual](https://docs.ankidroid.org/#_via_usb) ---
