When trying to access to self-hosted bitwarden im my PC using desktop App or browser extension it issues an error 
[2025-11-27 12:33:39.465] [error] {
  response: {
    error: 'invalid_grant',
    error_description: 'Auth-Email header invalid.'
  },
  statusCode: 400
}

Can access to the site and my collegues don't have any problema to access to the same instalation using site or extension or DesKtop App.

Please advise

@pestacio Welcome to the forum!

To cut to the chase: sounds like this issue: "Auth-Email header invalid" error when attempting to log into self-hosted vault · Issue #17415 · bitwarden/clients · GitHub

So, you probably have to update your server version. (assuming also, that it is not current)

A have check the server version with ./bitwarden.sh update and it stated that:

bitwarden.sh version 2025.2.0
Docker version 28.1.1, build 4eba377
Docker Compose version v2.35.1

Update not needed

And it’s strange because my collegues, that have windows OS use the extension + Desktop App connected to the same host without any errors.

2025.2.0 definitely is not the latest server version. I think you should have a look into that next: Self-Hosting Update: Migration to GitHub Container Registry (and update your server – BTW, also because of this: Software release policy — update your Bitwarden clients and server)

(The current server version should be 2025.11.x)

They might just not have gotten the updated (latest) client versions yet.

The upgrade to the infrastrure itself using ./bitwarden.sh updateself and ./bitwarden.sh update generate the upgrade and solved the problema.

Many thanks! :slight_smile:
