is the mender service file actually installed/enabled on your device? sudo systemctl enable mender.service sudo systemctl start mender.service if it still fails, then maybe take a look in /lib/systemd/system or other systemd service file directories to see if the service file is installed on the device ---

We did do a name change at some point and on recent releases it is called `mender-client.service`, so it could be that. ---

I would double check the device identity and public key that they are what you are expect as this is the information that is used to map physical devices to preauthorized devices. ---

It is in the client root filesystem as /data/mender/mender-agent.pem. If it does not exist when the Mender client starts, it will be created. Drew ---

HI Drew , i changed the public key & the device identity as (echo “Deviceid =raspberry”) . Snapshot of preauthorize is attached but when i am restarting the mender-client the device is neither reflected in pending nor accepted . i also check the client logs ,but didn’t find any thing ![pb](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/348021ed6e564842a506544ff40ff61528a40050.png) ---

Hi @arun it’s hard to say with the info provided. Can you provide the client logs? Drew
