Brave browser bitwarden addon

Hi!
I have installed a vaultwarden server with docker under ubuntu noble under my homelab; I can login in the web interface. I’ve installed the extension under firefox and all going good but under brave browser and vivaldi I cant login with the extension always said in spanish "Ha ocurrido un error inesperado.
The version I have installed is:
Vaultwarden 1.35.7
Web-Vault 2026.2.0

Thanks for your help.
Fernando

Why are you not using the latest release?

The issue (if not caused by an error in the Server URL configuration) most likely happens because you are using an incompatible client version, i.e. one that requires an endpoint that is missing in earlier versions of Vaultwarden.
