I just managed to add my YubiKey as WebAuthN device from a different machine running the same OS and using Brave browser. What's interesting is now I can also use it from my desktop and also remove and re-add YubiKey as WebAuthN from desktop.

This suggests that:

1. This is partially client-side issue, since the laptop worked
2. This is partially server-side issue, since the successful addition fixed it on a different machine

Thoughts?

Did you solve this? Timeout here as well.

[jakubgs]

I haven't seen this issue in a while.

But honestly, we barely use NextCloud because it's kinda clunky.

Failed here too on Brave (tested with a private tab too), successfully added FIDO2 key on Edge.
