Hello,  
I was testing mender with a qemu on which I had mender-client installed. I tried connecting my qemu to hosted mender but I never see any pending device.

Et sur qemu j’ai ce message :

```auto
Jun 16 17:13:26 localhost.localdomain mender[897]: time="2022-06-16T17:13:26+02:00" level=info msg="State transition: authorize-wait [Idle] -> authorize [Sync]"

```

I tried afterwards to decommission all my devices and retry to connect my qemu to hosted mender server but it fails with the following error :

Any ideas?  
Thank you

What do the client logs on the device say?

```bash
journalctl -u mender-client

```

Hello,  
It works now, I guess it was a synchronisation problem in the hosted mender web UI as no action I made on the devices (rejection/decommission/dismiss) was executed and my devices status were still accepted.  
Thank you
