Error disconnect
You should probably explain what kind of help you need. I can see your device disconnects from the server, but are you asking question in the server section of the forum? It looks like you have a device problem.
I dont know, the first 3-4 days everything was ok, and now is always offline. Any tips?
The main tip would be to contact device vendor support and get your device fixed or find out why it behaves like this.
