U2F error code 1 (OTHER_ERROR): device status code: 9210

[zxcvbn4038]

I am trying to register a u2fzero token and I get the error above. However the device does seem to work with Google and other sites that support u2f. Any idea what a code 9210 might be?

Looks like u2f.register is the source of the error, the u2fRegistered callback is being called with a resp object containing the error.

Hmm, i may be a bad token, looks like I can still use the key where it is already registered, but something is not working right when I try to register it.
