Hello,

i just want to set uop an Android MQTT Client.  
I tested several clients in the google plaground store, but i cant get any connections.

With the PC-Program MQTT-Explorer i can get a connection.

I followed the intruction on the MQTT-Integration side.

I testet the Server with Server: eu1.cloud.thethings.network  
Port: 1883. and also the IP-Adress 63.34.215.128

User name is application\_id@ttn and password is the API-Key.

What can be the problem?

Greetings

E\_T

Have you tried port 8883 and you need to use TLS. And what version MQTT broker are you using?
