How do I fix it?

Answer 1

This error is caused when you are not connected to internet. Check your internet connectino and try again

1. Check if you have added INTERNET permissions in the androidManifest file.
2. From the logs i can see that you are using google-signin so make sure you have uploaded the SHA-1 to the firebase console. If not then add the SHA-1 key and replace your google-service.json file with new one.
3. If running on an emulator check if the emulator can access the internet. More on this here

google is rejecting your request because your API is not enabled, enable maps SDK for android and IOS, then add your API key in the AndroidManifest.xml
