Hi, I tried to translate your question, and based on my understanding of your issue, this is the solution I can suggest. I hope it helps.
Based on the error message, it looks more like an authentication domain/network connectivity issue rather than an active session issue.
I would suggest checking:
1. Make sure the device is connected to the organization network or VPN.
2. Verify that the authentication/domain server is reachable from the affected device.
3. Check DNS resolution and network connectivity to the authentication server.
4. If another authentication account previously worked on the same device, test with that account to determine whether the issue is account-specific or device/network-related.
5. If the issue happens only to this user, check the user's account status and authentication logs on the server.
Since all sessions have already been logged out, I would focus on the network/domain authentication path first.

This behavior looks less like an aDesk session/logout problem and more like a Windows domain authentication / cached-credential problem on the affected VDI.
