No connection to nRF cloud (Attempts to use AGPS)

[Stas Jis]

We are using nRF9160 (Development Kit), SDK 1.9.1 board with "serial lte modem" firmware.
We are trying to get AGPS coordinates (using an external antenna), but for some reason we stopped receiving confirmations about the connection to the nRF cloud.
In response to the command "AT#XNRFCLOUD=1" we always get only "OK" without (#XNRFCLOUD: 1,0).
Checking the connection to the cloud shows that there is no connection:

AT#XNRFCLOUD?

#XNRFCLOUD: 0,0,16842753,"nrf-352656108600480"

The last time during development we checked the command sequence for getting coordinates using AGPS about a month ago and everything worked fine (was tested on SDK 1.8). But now even on SDK 1.8 we cannot get coordinates using AGPS, only regular GPS works.

i can confirm that your device has not connected to nrf cloud (via MQTT) since: February 21, 2022, 00:19:10 (UTC-0800)

i tested with a DK, 1.9.1 tag, and your prj.conf and it worked as expected.
you could try uncommenting: 
CONFIG_SLM_LOG_LEVEL_DBG=y
to get some more info.

or run asset_tracker_v2 on your device to see if it is able to connect to nRF Cloud.

Perhaps your SIM card is out of data or your device's nrf cloud credentials have been deleted/changed?

With this result:
2022-03-31T12:17:42.194Z DEBUG modem >> AT#XNRFCLOUD?

It is expected that you will get this result:
2022-03-31T12:17:36.432Z DEBUG modem >> AT#XAGPS=1,1

justin,
I included on CONFIG_SLM_LOG_LEVEL_DBG=y,
I am attaching the logs:
