mqtt.iotguru.cloud has IPv6 address in DNS, but refuses connections on IPv6

I am trying to add a connection to my IoT MQTT Panel in Android. I get an error "Unable to connect to server ...(IPv6 addresses) and ECONNREFUSED".

Testing from my workstation;

$ telnet -6 mqtt.iotguru.cloud 8883
Trying 2a01:4f8:1c1c:13f8::1...
telnet: Unable to connect to remote host: Network is unreachable
$ telnet -6 mqtt.iotguru.cloud 8883
Trying 2a01:4f8:1c1c:13f8::1...
telnet: Unable to connect to remote host: Network is unreachable
$ telnet -6 mqtt.iotguru.cloud 8883
Trying 2a01:4f8:1c1c:13f8::1...
telnet: Unable to connect to remote host: Network is unreachable
$ telnet -6 mqtt.iotguru.cloud 8883
Trying 2a01:4f8:1c1c:13f8::1...
telnet: Unable to connect to remote host: Network is unreachable

It looks like the App in Android doesn't switch over to IPv4 after getting a connection refused on IPv6.

I suggest that either the IPv6 AAAA-record should be removed from DNS, or better, get IPv6 answering on the service.

Hi,

Posted by: @onpa

is API REST working now ?

Would you try the following URL on your network?

https://api.iotguru.live/measurement/loadByNodeId/gy8rYTk1GxtKlbOwAM0R5w/temperature/DAY/288

https://api.iotguru.cloud/measurement/loadByNodeId/gy8rYTk1GxtKlbOwAM0R5w/temperature/DAY/288

hostByName(): DNS Failed for api.iotguru.live
1050017: {sendHttpValue(nodeKey, fieldName, value):234} - Response received from the cloud (status code -1)

It looks like a DNS issue on your side, your network cannot resolve the `api.iotguru.live` domain name to an IP address.

Hi,

I'm trying example with sending data from ESP32 to IoTguru, unfortunately I'm receiving error with DNS resolving API address...

Do you know, what is wrong ?

Example - https://github.com/IoTGuruLive/theiotguru-arduino-library/blob/master/examples/02_send_measurement/02_send_measurement.ino

1050009: {sendHttpValue(nodeKey, fieldName, value):223} - ENTRY
1050009: {sendHttpValue(nodeKey, fieldName, value):225} - Send request to the cloud
hostByName(): DNS Failed for api.iotguru.live
1050017: {sendHttpValue(nodeKey, fieldName, value):234} - Response received from the cloud (status code -1)
1050026: {sendHttpValue(nodeKey, fieldName, value):236} - EXIT

Thanks,

Ondrej

RE: Copy Dashboard config to new device

Is there a way to copy the Dashboard config to a new mobile device? (as it is not stored in the cloud)

At the moment, no... but I've just added it to the todo list, I'm working on the Android app already. I planned a release at the middle of the next week.

RE: Update multiple fields of same node

Using rest API how can I write the data to multiple fields of the same node?

Like I want to write the temperature and humidity fields that are in the same node.

At the moment, it is not possible with the REST API, you need two separated calls, but you can send two request in the same HTTP channel with reuse on:

http.setReuse(true);
