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