Cannot get data from your system

[Ayo91]

I installed Minera in rasberry pi B+ and it works fine. However, I have installed the client of getminera app with the command:
url -o- https://raw.githubusercontent.com/getminera/client/master/install.sh | bash -s xxxxx

And Minera portal shows me this message: Cannot get data from your system. I have rebooted my device, reinstall but there is not way to get it works. Should I open some ports in my router?

I have tried several things during these days but its imposible. Any help?

Edited: the log file of minera-client shows this message several times: Socket reconnect error {"type":"TransportError","description":503}

I probably found a problem with the DNS.
Please can you retry now?
