Problem with system -> Check packages

Hi I have a Mikrotik RB1100AHx2 with the latest firmware 6.43.4 that I upgraded manually becasuse the check packages fails. I have 4 wan with firewall load balance. All works correctly but If I open a terminal and make a ping to google, not work. I have set the DNS correctly. Could you help me ?¿ If you want i cant put my configuration.

Thanks
