Bitwarden clients no longer working with Vaultwarden

[andreasdueren]

Seems to be a windows issue https://github.com/dani-garcia/vaultwarden/issues/7462. One of my user resolved this by downgrading their extension: https://addons.mozilla.org/en-US/firefox/addon/bitwarden-password-manager/versions/

@andreasdueren that explains it. I'm still on 224H2 as my PC's refuse to update past that because of all the windows de-spying hacks/tools that I've used. Sticking it to shitsoft is paying off in dividends

This is not just a Windows Issue @andreasdueren. We have this problems on machines Running the newer client version 2026.08 on Windows and Linux devices,
There is already an update https://github.com/dani-garcia/vaultwarden/releases/tag/1.37.2 for vaultwarden that should fix this.

Had the same problem with LibreWolf on WIN. Removed and reinstalled Bitwarden Add-on. With new version of Vaultwarden, all is working now. Thank you @james

For me it stoped working yesterday. Web-UI is still working.

Installed Version on Cloudron is:
App title & version - Vaultwarden 1.37.2
App ID - 9ed63d4d-a7ce-4e86-9dfd-60b08fd8ffd2
Package version - com.github.bitwardenrs@1.26.2

Tested and not working on my system:
DISTRIB_ID=Pop
DISTRIB_RELEASE=22.04
DISTRIB_CODENAME=jammy
DISTRIB_DESCRIPTION="Pop!_OS 22.04 LTS"

Tested as Browser-Extension:
Brave - Bitwarden Version 2026.8.0 (https://chromewebstore.google.com/detail/bitwarden-password-manage/nngceckbapebfimnlniiiahkandclblb?pli=1)

Tested OS native app through Pop!_Shop:
Bitwarden
Version 2026.8.0
SDK 'main (eb825d5)`Renderer 150.0.7871.129
Node 24.18.0
Architecture x64

Observed behaviour:

• Web-UI of Server working, password and authentication workflow confirmed here
• Authentication error "Wrong Password" on trying to login for an already logged in Client
• Disconnecting and Re-Authenticating the Client to the Server leads to successfull log-in but no entries being visible and non of the tools/features like "Help > Troubleshooting > Download diagnostic report" and other features working

After some more fiddling around and re-installing both the server and the clients, it is now working on my system again. Not entirely sure what changed as the reported installed versions are the same as before but now it is working again.

We mostly use the Edge Extension we had too reinstall the extension on all Machines after updating the server than evrething worked again.
