I'm trying to connect to nRF cloud but it doesn't work anymore. Even your samples like Asset tracker v2 an MQTT multi service sample can't connect to the nrf cloud anymore. Is there a problem with the servers or something else? The error I get is:

%CESQ: 64,3,24,3
[00:00:38.524,078] <err> nrf_cloud_integration: NRF_CLOUD_EVT_TRANSPORT_CONNECT_ERROR: -3
The -3 according to your documentation means a network error.
