Hi Aatif, to upload the certificate, you need to give your username not the tenant id in the command. Please try again with your username. ---

Hi Aatif, error 401 means [credentials are invalid](https://cumulocity.com/api/core/10.16.0/#operation/getCurrentTenantResource). Please make sure the combination of user and password is correct. The second password you enter should be the password of your Cumulocity account. You can also use `tedge config list` command to check if the URL and other settings are correct. ---

Are you using a single sign on user, as I believe this is the default for trial tenants (though I’m not 100% sure about this). If so you can create another user in your tenant which has the “Tenant Management” permissions to use for the certificate uploads. Alternatively you can always manually upload the device public certificate in the Cumulocity IoT Device Management UI. 1. On the device, display the certificate on the console (if you get permission denied, then run the command again using `sudo`) 2. Copy the printed certificate text (including the `-----BEGIN CERTIFICATE-----` and `-----END CERTIFICATE-----` lines) and save it to a file on your local machine (e.g. `device-001-certificate.pem`) 3. Open a browser and navigate to your Tenant, and open the **Device Management** UI application 4. Navigate to `Management` \> `Trusted Certificates` 5. Click `Add trusted certificate` (in the top right corner). Activate `auto registration` and `Enable` options. (Note: the certificate name does not matter too much, but using a descriptive name is always helpful for your future self). Upload the certificate file you saved locally in step 2. 6. On the device, you can speed up the reconnection attempt by reconnecting ---

**Note** Your Cumulocity IoT user must have the `Tenant Manager` role (and adding this will require you to log out and log in again in the UI) ---

I checked - there is no tenant [https://aatif312.cumulocity.com/](https://aatif312.cumulocity.com/). That’s why you get the 401. Why do you think this is the tenant url? ---

Yes I have created one tenant from the administration account ![image](https://europe1.discourse-cdn.com/flex005/uploads/cumulocity/original/3X/8/e/8e53c2fbdafa957c8d67e406d580c78eee786116.png) ---

What you are showing me there is a user account, with Tenant manager permissions. What is the tenant in which you are doing this? What is the url in the address bar at the top of the screen? ---

In your case the `c8y.url` should be ```auto aatif312.eu-latest.cumulocity.com ``` You were incorrectly using `aatif312.cumulocity.com` before. ---

The user aatif312 does not exist. Instead you should a user name that is provided in your user management view you’ve posted above (and have the Tenant Manager role). I think you have common misunderstanding about tenants and user… What you’ve created is a user in a specific tenant. ---

What you think is a “user” is actually a tenant. When you do this: `tedge cert upload c8y --user "aatif312"`there is no user “aatif312” in your tenant “aatif312” but users systemuser, aatif\_jariwala2 … etc. ---

The tenant is [aatif312.eu-latest.cumulocity.com](http://aatif312.eu-latest.cumulocity.com). On that tenant there are four user accounts one of which is ‘aatif\_jariwala’. It is this account you should specify as --user in the tedge command, and when prompted type the password for it.
