Putting this here to log this & give a bit more data - I am also having the same issue since this morning 7 Jan. Am in Singapore. Have never encountered this previously! I’m hoping it will resolve on its own, and will update if it does. - When I tried to sync Ankidroid (on a Google pixel phone, on wifi) to Ankiweb, this error message appears: “ **a network error occurred. Error details error sending request** ” - and can’t do anything else. - I deleted my Ankidroid app (has antivirus) and re-downloaded it onto my phone. At the opening screen after keying in my user ID/pw, I typed “sync from Ankiweb” and the same error message appeared. Tried this using both home wifi and mobile network - but same issue persists - I got onto my laptop (no antivirus), where the official anki app is installed, and try to sync - and the same error message appears - I’ve downloaded WINMTR to see if there is a packet loss issue. It’s still running…but seems like there is some? ![WinMTR ankiweb](https://us1.discourse-cdn.com/flex002/uploads/anki2/original/3X/4/3/430ef85033d24d42e8ba28842d82375b23122ccc.gif) Not sure I want to introduce more variables to my problem with manual transfer - so I’ll just wait and see as suggested! Thanks for taking the time to read all these posts in the thread. Must be rather overwhelming. Hope it helps to know that 99% of the time we’re having a great time on Anki 💪 @Danika_Dakika ---

Hello everyone! I just wanted to say that I am running into the same issue. I am based in NYC, and I have been encountering this problem since this morning. **Exact error message:** > “Error. A network error occurred. Error details: error sending request for url ()” **Key details:** - Occurs on **multiple devices** (desktop Anki + AnkiMobile on iOS) - Occurs on **multiple networks** (home Wi-Fi and cellular) - I can **log into AnkiWeb successfully via browser** - I am running the **latest stable versions** of Anki on all platforms - Logging out/in, reinstalling, disabling VPNs/firewalls, checking system time, launching in the safe mode, and other standard troubleshooting steps did not resolve the issue I hope that this problem is able to resolve on its own in a timely manner, but I will keep an eye out for any manual solutions. At the very least, I hope that my own attempts to solve this problem can assist in diagnosing the cause. Thank you to the Support Team in advance for working to improve the situation! ---

+1 on NYC location. Started today around 4:30 pm (12/6). Doesn’t work on iOS, Linux OS (Desktop), and Windows OS; multiple networks; ankiweb works; no firewalls. Based off of previous replies this seems to be Anki servers blocking traffic rather than user issue. Perhaps services used by Ankiweb like cloudflare are inapproriately blocking out requests. ---

Hi, My Anki sync fails instantly with “A network error occurred – error sending request”. Details: - Happens immediately (~0.5 seconds) - macOS desktop (latest Anki) - iOS AnkiMobile - Multiple networks, VPN on/off - Add-ons removed - Database checked I can access [https://ankiweb.net](https://ankiweb.net/) normally (curl works, website loads). Could you please reset or repair my AnkiWeb sync state? Thanks! ---

I’ve also got a 404 from this URL. And I can’t sync Anki laptop + AnkiMobile on IOS, but I can log in my AnkiWeb without any problem. It started about a few hours ago (07/01/2026). Hope this problem will resolve soon. I’ve been using Anki for about a year, but I’ve never encountered this before ---

I updated the SSL certificates weeks ago in preparation for this expiry, but it seems like the update failed to apply to one server. ☹ Things should be working again now, and my apologies for the inconvenience this has caused to the affected users. ---

My sync still shows the same error, and I believe it is because something went wrong mid-sync and my Anki will refuse to restart the sync. Please help soon ---
