Register a WebAuthn device error

Hi,
I have a problem adding my yubikey to 2FA. It reports an error:

Gitlab runs on a Synology NAS. In the preview, I did not find anything about this problem in the configuration. Here is my configuration.

Thank you very much for help with this problem.

The report provides a Docker Compose configuration using sameersbn/gitlab:16.6.1, but names no repository file, test, or source entry point. Start by reproducing WebAuthn device registration with this image and configuration, then inspect the reported error and relevant container logs. Done would require identifying the cause and documenting a verified configuration or compatibility fix.
