The server details - www.beavernews.net Port - 9999. Topic name - data/upload . Message format - (001,941,1755,1726,25300,32.69,0,1710) 

I used a mobile app https://play.google.com/store/apps/details?id=com.sanyamarya.mqtizermqtt_client  , set the SIM for IPv6 only and we were able to see the data being  posted. The data can be  viewed at http://www.beavernews.net:8090/rawData

Hi,

vkadal said:

The server details - www.beavernews.net Port - 9999

That domain doesn't support ipv6. Only the ipv4 address is returned:

$ nslookup www.beavernews.net
Server:		127.0.0.53
Address:	127.0.0.53#53

Non-authoritative answer:
Name:	www.beavernews.net
Address: 64.111.109.81

 

Please google "ipv6 dns lookup" for online resolvers to verify if your broker has ipv6.

 

Kind regards,

Håkon
