• Examine Your Internet Connection-The simplest way to resolve the Google Play Store error is to verify that your internet connection is functioning properly. It is possible that the Play Store will be unable to connect to Google servers at times. So, as a quick remedy, try switching between Wi-Fi and mobile data to see if that solves the problem.
• Force-quit the Play Store app and relaunch it.-Swipe up from the bottom and hold in the middle of the screen if you're using fullscreen gestures on your Android phone. Then, on the Play Store app card, slide up (or right/ left in some custom skins) to force exit the app. Return to the App drawer and relaunch the Play Store to see if the issue has been resolved.
• Check There isn't a Time and Date Mismatch - Scroll down in the Settings app until you reach the 'System' section. To access system settings, tap on it. Select 'Date & time' from the System menu and enable the 'Set time automatically' and 'Set time zone automatically' toggles. If they aren't already turned on, turn them on to automatically set the time and date on your phone.
