Tried out above and it worked! Specifically, I had to set the following variables in my .env file:
FLUXER_PASSKEY_RP_ID=fluxer.domain.com
FLUXER_PASSKEY_ADDITIONAL_ALLOWED_ORIGINS=https://fluxer.domain.com
as well as in my docker-compose.yml file:
  FLUXER_PASSKEY_RP_ID: ${FLUXER_PASSKEY_RP_ID}
  FLUXER_PASSKEY_ADDITIONAL_ALLOWED_ORIGINS: ${FLUXER_PASSKEY_ADDITIONAL_ALLOWED_ORIGINS}
The https:// prefix for ALLOWED_ORIGINS is necessary. Thanks for the help, @probablyjassin!
