Today's headline mobile phone application always prompts that the network error cannot be refreshed! Solve!

1. From the literal meaning of this error prompt, it is very easy to understand, because there is a problem with the network connection of the current mobile phone. I believe that everyone is familiar with the picture below, and you need to verify the update before the system update. Because the content and model of each update are different, the updated capacity is different, big or small.

The first time I encountered this problem was when my mobile phone downloaded the update and was ready to verify it. By default, the mobile phone will lock the mobile phone in a black screen, such as 1 minute. If the capacity of the update package is large, the verification will take a long time, more than one minute. At this point, when we unlock the screen again, we will see the prompt "Because you are no longer connected to the Internet, the update cannot be verified".

The reason is that Apple's iPhone will enter a power-saving state after the screen is locked and the applications that want to access the network will be blocked. So, if this is the reason, you can touch the screen during verification to ensure that it will not lock the screen with a black screen.

If you don't belong to the above situation, please continue to look at this method. The above is because the mobile phone can't access the network after the screen is locked, but there is another situation in reality, that is, there is a problem in the network between the mobile phone and Apple's remote service, just like the car is stuck in traffic.
