Hi all,
first thank you for your great work! It took me a while, but now my private vault server is running. 
Unfortunately, I tried to register my YubiKeys like I did it on Bitwarden Cloud. The keys worked there. I hope someone can help me to get it running on my own Vaultwarden server!
Here is the log:

I wanted to see more details, but even debug level did not create more output.
Here is my config:
