Occasionally you might encounter this error when launching the Google Play Store. Even tapping on the Retry button doesn't yield any results. Here are 2 steps you can take to resolve this.

 

Clear Google Play Store data
Settings > Installed apps > Google Play Store > Clear data

Re-login to Google Play Store
Settings > Other accounts > Google > Three dots (More) > Remove Account

Once that completes, launch Google Play Store again and it should prompt you to login to your Google account.
