For the connection to work, your internet router must allow access to some technical ports. Please make sure these are not blocked by your router or internet provider:
- 443/TCP – needed for secure internet communication (HTTPS)
- 8883/TCP – needed for secure device communication (MQTT)
- 53/UDP – needed to find servers on the internet (DNS)
- 123/UDP – needed to keep the device time correct (NTP)
