Glowstick seems to be struggling with internet connection.

I've recently started experiencing issues with my CAD GlowStick connecting to internet / Wi-Fi but not quite sure what's causing it.

Now I did change my WiFi APs a few weeks ago and this happened around a week later, however I'm not sure if this is related as every other device on my network (including many ESP8266 / ESP32 based devices) have been fine. I've also tried with a separate SSID that only the stick is connected to and WiFi Channels 1 & 6 (20Mhz).

The stick itself when I reboot seems to flash the WiFi LED green for quite a while, and eventually it turns to red.

From what I can see the actual stick is connected to the WiFi AP based on the APs logs. My router also confirms that it's online with an active IP lease too.

I can also see the stick despite showing red for the WiFi LED, that it's actively making DNS lookups to ntp and a subdomain that then is for Glow (.cad.sensornet.info) making me think it might not actually be WiFi related.

Any help with diagnosis would be appreciated.
