Hello @gusto sorry to say but BitwardenRS is not the official Bitwarden docker, but another 3rd party service that has now been rebranded under the name of “Vaultwarden”.
I would either suggest reaching out to the proper support community for the server software you downloaded, where the Vaultwarden forums can assist with your issue.
If you want to instead run the official and vetted Bitwarden server you can either chose to use the standard installer, or the new Unified installer (which is still in beta).
