Please help. I cannot invite new users.
User is invited from admin panel (Users), and user receives an invite. User clicks “Join Organization Now” button in the email and proper instance of vaultwarden is opened, but there is an error in the upper right corner:
Unable to accept invitation. Please ask your organization administrator to send you a new invitation.
(Error translated from my language).
I’ve tried a couple of things but none is working for me.
No errors in the container log, and no errors in browser console.
My setup:
- vaultwarden self-hosted on homelab (container image up to date)
- using cloudflared to access it with custom domain
- temporarily enabled user registrations
- sending email via SMTP with external provider
