Hello i'm not able to send values to Thingsboard from node red using mqtt.  
Broker = [demo.thingsboard.io](http://demo.thingsboard.io)  
port = 1883  
topic = v1/devices/me/telemetry  
copied the correct access token multiple times.  
have tried sending this  
{  
"value" : 25  
}  
in template node, inject node, and also tried json node. no luck.

Have seen this issue here before, but not a good solution that actuall worked for me.

Thanks

best regards

ok so if i use [cloud.thingsboard.io](http://cloud.thingsboard.io) instead of [demo.thingsboard.io](http://demo.thingsboard.io) it works.  
Any idea?

without showing us any errors from the logs then only guess is that the token for one is not the same as the required token for the other.
