Attempting to connect to server message

[AndreiP 33]

Hi, 

Everytime that I open the app (doesn't matter on which device, Samsung tv, android app, Sony tv or my android cell) I've got this message (2-3sec). I can access and watch my media after. But I just want to ask why it started to appears, I didn't change anything in my devices. 

Maybe just to be sure why it's not like before. 

Windows server 4.10.1.0

Thank you.
