Proof of possession fails for trusted certificate

Forum

Hi,

I have created a root cert with openssl and a device cert and key signed by the root cert.

I then upload the root cert to Cumulocity and try to establish proof of possession but I always fail at that step. I create the signed verification code fine and check for newlines but I always get: Cannot verify signature for certificate with fingerprint: e9a62fb7e97083b6c and tenant id: t2081875008.

Do I need to establish proof of possession or is that only needed for the bootstrap process?

I must be missing something as this is pretty straightforward. Any suggestions?

thanks

Hello,

I followed the guide closely and I get stuck here Device certificates - Cumulocity documentation

with the above error I mentioned. As I understand it, performing proof of possession is necessary for connection to be established.

thanks

Hello,

I have tried multiple times.

I create certificates based on your guide and then try to connect both with my device and with a leshan java client. Both error out. I am also unable to succeed in the proof of possession part..

I am not sure what exactly would be helpful for you to know regarding my setup. Please ask away.

Is there an instance where I could test my device against Cumulocity? Meaning, could you provide me with working certificates (you can send me via pm if possible) so I can reliably test my setup?

thanks
