Phase vault provider: testConnection fails with "401: Token expired or deleted" using a valid Service Account token #5511

To Reproduce

1. In Phase Cloud (console.phase.dev), create an app.
2. Enable SSE (server-side encryption) for the app.
3. Create a Service Account, attach the app to it, and generate a Service Account token.
4. In Dokploy, add a new Phase vault provider and paste the Service Account token.
5. Click Test connection.

Current vs. Expected behavior

Expected: the connection test succeeds.

Actual: the dashboard returns:

[{"error":{"json":{"message":"Phase: authentication failed (status 401: Token expired or deleted)","code":-32600,"data":{"code":"BAD_REQUEST","httpStatus":400,"path":"vaultProvider.testConnection","zodError":null}}}}]

The token is freshly created, not expired, and not revoked.

Provide environment information

Operating System:
  OS: Ubuntu 24.04.4 LTS
  Arch: x86_64
Dokploy version: v0.30.7
VPS Provider: Hetzner
What applications/services are you trying to deploy?
  Phase.dev (Cloud) as secrets/vault provider

Which area(s) are affected? (Select all that apply)

Application, Docker Compose

Are you deploying the applications where Dokploy is installed or on a remote server?

Same server where Dokploy is installed

Additional context

• Phase Cloud is used, not self-hosted, so the default API host is expected.
• The request is made server-side by Dokploy, so it can't be seen in the browser DevTools. docker service logs dokploy shows no extra detail about the outbound request (URL, auth header format), so I couldn't debug further.
• The Phase provider was added in feat(vault): add Phase.dev secrets provider #5123 / feat: add Phase.dev as a secrets provider #5122.
• Suggestion: log the Phase API URL and the auth scheme used (without the token) when testConnection fails, to make this debuggable.

Will you send a PR to fix it?

Yes
