Hi,
I stumbled into a problem when generating CSR
I follow the procedure located here https://github.com/nRFCloud/utils/blob/main/README.md
I have issues generating this using my own application, but I can reproduce the same result using the "location sample".
I'm using the location sample found here: github.com/.../location
when the device is trying to generate the private key + csr the device stop responding.
device_credentials_installer -d --ca *_ca.pem --ca-key *_prv.pem --coap --verify
I've tested this on both the nRF9151DK and the Thingy91x
the following output is from nRF9151DK using SDK 3.0.2
After a bit of investigation I found out that when I run: AT%KEYGEN=16842753,2,0 I get:

If I try the same procedure with the at_client sample I get a more desired output:
