Yes, I overwritten the certificates because I let DK connect to AWS. The original one is removed.

now I'm ok. I figured out the reason

You shouldn't need to set certificates to access the cloud if you're using a DK. The DK comes with certificates already flashed, so it shouldn't be necessary. Have you overwritten the certificates at some point?

nrf_cloud_agps first connects to nRF cloud and then download AGPS data. So The device must have certificates for nRF cloud. I think.

If I understand in a wrong way, please point it out.

Do you need to set certificates to download AGPS data from nRF cloud?

I tried the same program with different PC, DK board, and SIM. I disabled PSM and don't modify other parts in nrf_cloud_agps from the original

I got another error.

backend->api->connect(backend) causes an error

<cloud.h>

static inline int cloud_connect(const struct cloud_backend *const backend)
{
	if (backend == NULL || backend->api == NULL ||
	    backend->api->connect == NULL) {
		return CLOUD_CONNECT_RES_ERR_INVALID_PARAM;
	}

	return backend->api->connect(backend); // CAUSE ERROR
