Yes, that is currently impossible. As explained in the wiki this can happen when there is a breaking change made by Bitwarden, since we don't control the clients (and can only make sure the web-vault is compatible). So until we implement the new API, Vaultwarden is currently not compatible with clients with version 2026.5.0 (or later). Cf. https://github.com/dani-garcia/bw_web_builds/pull/245

It applies to everything that uses the new registration API. I don't want to come across as rude but this bug report is specifically about registration and likely has nothing to do with connecting an extension (as far as I've tested it that still works without issue). Since the issue tracker is not meant as a support forum I want to ask that you open a separate thread in discussions and provide more details like the support string from the Vaultwarden admin panel.
