Hi,
I have several deployed devices that have been running for a while, using the nRF Cloud A-GNSS system with the nRF Location library. These devices were successfully provisioned with nRF Cloud, and their public keys were uploaded. They had been functioning properly for about a month, but starting a few days ago, I suddenly began receiving authentication errors.
There have been no changes to the firmware or nRF Cloud configurations. My NCS version is 2.6.0, and the modem firmware version is 1.3.6. I used the AT%KEYGEN command to generate credentials and uploaded the decoded credentials to nRF Cloud, following the official tutorial.
Is there an issue with nRF Cloud that could be causing this problem?

[Update]: Our logs show that the last successful request to nRF Cloud was on February 5, 2025, at 02:20:30 UTC. Since then, all requests have been rejected due to authentication errors. There is a maintenance report for nRF Cloud on the same day: https://status.nrfcloud.com/maintenance/507661. I wonder if this could be the cause of the issue.
