Account sync error - "AnkiWeb service error" after multiple network changes

Hello, I have been unable to sync on iOS for several days. I always get “AnkiWeb service error” on both iPad and iPhone. I have tried multiple WiFi networks, cellular hotspots, reinstalled the app, and logged out/in multiple times. The AnkiWeb website itself loads fine, but syncing always fails. I believe my account may be locked on the server side. My AnkiWeb email is:1298458127@qq.com. Please help me reset my sync state. Thank you!

There is an active issue with AnkiWeb – Account-specific sync failure on Anki Desktop and AnkiMobile – but that hasn’t been going on for days, so I don’t think that’s what has been causing problems for you.

Once that issue is resolved, I will be able to look at your account. But if you can access it on the AnkiWeb site, it seems unlikely it is locked.

There are other things you can try – Error establishing a secure connection when syncing - Anki FAQs – but wait until the active issue with the servers is resolved.
