<environment>- Windows10- nrf v1.3.0- modem v1.2.0- DK 0.9.0
I get "CLOUD_EVT_ERROR" when using nrf_cloud_agps. There is an error saying "Connection was closed, possibly by cloud".
I read this page https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/nrf_cloud_agps/README.html

I turned off PSM by CONFIG_LTE_POWER_SAVING_MODE=n
but same.
Do I have to set up on nRF Cloud to use this program?
Thank you in adavce!
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

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