Help with troubleshooting

I'm having trouble with the server v2 not connecting. Server v3 appears to be fine. I see the following:

  • config list network shows dns: 192.168.1.1
  • Unbound sees zero queries from the module when V2 tries to connect
  • Cellular DNS resolves correctly via AT+CDNSGIP
  • V3 MQTT works fine over WiFi to local IP

TIA!

config list network shows dns
  • config list network shows dns: 192.168.1.1

Sounds like you configured your DNS to use your Wifi DNS, but that won't work when out of range of wifi and on cellular networks.

Suggest to set to standard DNS servers (1.1.1.1, 8.8.8.8, etc).

Back in the country,

Back in the country, apologies for the delay. Thanks for your reply. That's now fixed, but I appear to have a timing issue during boot, specifically "netmanager: MODEM up (with WIFI client up): staying with WIFI client priority". Is this preventing the cellular from working at all?
