SOLVED: Can't connect to server

[yacaquepongo]

I have two TVs (LG WebOS and Android) and both of them are having problems to log in, and so does my phone, but I can use JF normally with my PC.

The error message on my LG TV shows "The request timed out", while on the Android TV says "Can't find any servers in the local net".

Until now, I tried these things, but with no results:

1. Verified that my computer and the TVs are connected on the same network.
   
2. Restart JF
   
3. Update JF version from 10.10.3 to 10.10.7
   

I suspect it might be something silly and simple, but I'm really getting out of ideas. Any ideas of what the problem could be?

Thanks in advance
