What told you?
I have never seen that type of message on my phone.
Now it tells me that my its unable to connect to my server. Everything on my CPU is fine. Works great. The cpu has internet connection. Says verify its up and running and has a connection. Yes to both.
It kept saying I need an update but when I would go to update it would tell me it had issues.
