Web Vault not syncing

I’m new here and I have a problem with syncing also.
I installed a few days ago Bitwarden self-hosted on a ubuntu server.
I chose the paid version of Bitwarden.
Everything was ok and syncing until I added my Yubikeys.
I use a Macbook with Mac app Bitwarden, also a browser extension.
My web volt is emty, but my ubuntu server volt is syncing with Mac app and browser extension.
What can I do to get sync also on web volt?
I tried to log out from Mac app and browser extension but this is not working.
Thank you!
