Relevant info:
- Windows 10, I did not update my OS or change any Internet-related settings
- I’m using Anki 24.10 RC2 (898c9128). Downgrading to RC1 (8d9251e7) doesn’t help
- I am not using a proxy
- Syncing was working just fine yesterday, same Anki version, same everything
- Add-ons can be updated, so this problem is related to syncing but not add-ons…somehow
- Everything other than Anki is working fine
- None of the topics with “Error sending request for url ()” (which seems to be happening since at least 2021) contained a working solution
- Rebooting my PC doesn’t help
