One of the main reasons for the internal exception error can be that your internet service provider might have been facing temporary issues with its DNS server.

Do you wish to find the DNS address of your system? Here you go –

Head towards your modem administration panel or router administration panel of your device and it will be typically set automatically.

This will allow all the routers to switch to DNS servers that you have specified manually, usually, there are only two of them. You should also try entering the below-mentioned values for switching to DNS servers of your choice –

  • Primary DNS address server:
  • Secondary DNS address server:

When you enable these new DNS server settings, then it will automatically connect your system to the own servers of Google whenever it is trying to connect to something from your device.

What if even this solution doesn’t work for you?
