Uno R4 WiFi not connecting to iot.arduino.cc

Development Tools Cloud IoT

Hello all,

Just started with Arduino and facing connectivity problems.

Obviously this problem has popped up frequently in forum discussions but so far I have not been able to solve the problem.

Here is an example of Serial Monitor messages:

***** Arduino IoT Cloud - 2.3.1 *****
Device ID: 9d1cd65b-f876-4ef5-af5f-79c9fe7a7970
MQTT Broker: iot.arduino.cc:8885
WiFi.status(): 0
Current WiFi Firmware: 0.4.1
Connected to "Himmelriiki-2G"
TimeServiceClass::getRemoteTime cannot get time from NTP, fallback on connection handler
TimeServiceClass::getRemoteTime cannot get time from connection handler
ArduinoIoTCloudTCP::handle_SyncTime could not get valid time. Retrying now.
ArduinoIoTCloudTCP::handle_ConnectMqttBroker could not connect to iot.arduino.cc:8885 Error: -2

...and so it goes on indefinitely.

I have uninstalled and reinstalled every component, the Uno firmware is the latest version. I checked the firewall settings (Windows 11) and can't find anything. The SSID password etc. is correct.

I am running out of options. What should I try next?
