Android cannot open Google Play

 Greetings from Amoy! (Xiamen, China),

Today I faced, for the umpteenth time, the error message when trying to access Google Play from Android,  Authentication is required. You need to sign into you Google Account. But I could not sign in, even though I was signed in to Google on Mozilla. The answer turned out to be part of another problem--both easily solved. So I simply copy below the other post. I've faced this same issue 6 times over the years--with Android, PC and iPhone, and the solution is so simple that I overlook it each time and waste hours. I've no idea how it happens in the first place, but hopefully in future both you and I will think of simply checking the date (including year).

 When connecting to the internet on Android, Mozilla Firefox said "This connection is untrusted." I knew there was no problem with the connection, so I clicked, "I understand the risks," and then "Add a permanent exception."  I was then able to go onto websites, but I had to keep adding exceptions--and Android Gmail absolutely refused to work, though I could check Gmail with Firefox.

Worse--I could not get into Google Play. It kept saying "No Connection" and "Unfortunately, Google Play Services Has Stopped." And als, Authentication is required. You need to sign into you Google Account.

I finally found that, somehow, my date had changed to the year 2019. No idea how, as I'd not changed any settings. I changed it back to 2014, rebooted--and everything works perfectly now.

There may be other reasons for your problem, but after having done this, I remembered I had faced the same issue twice before on Android and twice on my PC (and once on an iPhone). So when stuck, go the easy route first. In this case, clear the apps caches and reboot, but if that doesn't work, confirm you have the right date (including the right year!). If that doesn't work, remove and reinstall your Google account. And if that doesn't work....

Well...so far, I've not encountered a situation where none of those work, and I take care of, all total, about 11 devices.

Warm regards from Amoy, China!
