Hello,
My indoor device has recently started displaying “AG Server N/A”. I connected a USB cable to my computer and dumped some logs.
Here are some snippets:

I thought I was failing to connect to the WiFi, but I can actually ping the device, so it seems WiFi is working. Anything I can try?
Thanks!
