You're using your Android device and you know you're connected to the Internet (for instance, your browser works just fine), but you just got this message trying to connect to the Google Play Store. It makes no sense, because you can go right back into the browser and cruise the 'Net as usual. No connection problem there at all! This happens on devices that have never connected to Play as well as those that "used to work fine."
After much head-scratching and muttering, the answer became crystal clear. This is one of those "Doh!" moments, especially if you've done a reset on this device recently. The DATE and TIME are wrong.
Many devices, especially "unconnected" tablets, do not synchronize the internal clock when you perform a reset. Instead, they set the time to a preset date and time. A popular choice, for reasons only known to device manufacturers, is December 31, 1999 at Midnight. Strangely, the Time Zone is often unaffected by a reset.
NOTE: It is not always a good idea to update the original Market app. Some tablets do not work well with the newer Play app. If you've updated your Market app, try removing the update(s) and returning it to the original version that came with your device. If it is again able to reconnect, DO NOT allow it to update EVER!!! Not automatically. Not manually. Not EVER! You will have to go into the settings for the Market app and uncheck the auto-update checkbox.
PLEASE DO NOT WRITE US IF YOU HAVE TO REPEATEDLY UNINSTALL AND REINSTALL AFTER YOU UPDATE TO THE PLAY STORE. AS NOTED ABOVE, IF A NEWER VERSION IS INCOMPATIBLE WITH YOUR DEVICE, DO NOT USE IT. INSTEAD, REVERT BACK TO THE ONE THAT WORKS AND KEEP IT THERE.
!!! YOU MUST KEEP THE VERSION THAT WORKS !!!
Unfortunately, we don't have a solution for you yet. Some people have commented their devices work, but have not provided clear instructions for the rest of us. If you are one of these people, please let us know what you did. If you'd like to help us troubleshoot, please email us. Include as much specific information as you can.

PLAY STORE UPDATE:
In late April, 2013, the Play Store got a makeover. If none of the solutions below have helped you, try a quick update to your Play Store. This is usually done automatically when you try to use the app, but sometimes needs a little help from a desktop login and push to your device. If it's still not connecting properly, simply uninstall the update. No harm, no foul.
Correct the date and time on your device and try again. You should be able to connect now.
If you have a device with a Reset (button or hole), try a simple reset. If not, try removing your battery for about half an hour and try again. If you can do neither, let the battery drain completely (until it powers off due to low battery), wait half an hour, then charge it up until it's at least 10% charged before trying again.
Go to settings>apps>all scroll to Google app store and tap clear cache>clear data>force stop. Now restart your device and connect to the Play Store. Here's a link to the entire conversation. Thanks, Jeffrey!
Uninstall any apps you have installed that you don't use anymore. Sometimes, it's simply a matter of apps taking too much room on your device. You can do this quickly and easily using Settings > Applications > Manage Applications. Select the app you want to remove, the choose Uninstall. You will be prompted for confirmation before the app is removed. A few seconds later, you should have more room in your device's internal storage. Of course, if you're using an app that allows you to move your apps to your SD card, the amount of room freed on the internal storage will be much less. In that case, you may need to remove multiple apps.
If you have changed your Google/Gmail password recently, you will need to update your login password before you can get into the Play Store. Some devices make this easier than others.If you are having trouble figuring out how to update your password, try this article. Sometimes, changing your password will force the issue to correct itself. Be sure to make a note of your new password if you take this path.
One of our fabulous readers (the ever-popular and prolific Anonymous from the comments below) found that if you have installed the "Freedom" app, try restarting or uninstalling/reinstalling that app. Any app that temporarily blocks the Internet (your Firewall or your phone's built-in Airplane Mode setting) either partially or completely, should be tested to see if it is interfering with your ability to connect. Do this by stopping, disabling, or uninstalling it. Just remember to turn your Firewall back on when you are done!
If your device is a cellular telephone, have your Internet carrier's Tech Support Experts check that your phone is fully synchronized with their system. We recently had a prepaid phone with this problem and ended up calling our carrier. Apparently, the phone was only partially sync'ed with their system. We could do some simple accesses, but most browsing and Play Store access were out of the question. Most sites would not load completely, and we often saw "Server Not Found" errors. One tech wanted to replace the phone, but we weren't convinced a replacement phone was the answer. An account reset worked as a short term answer, but the problem resurfaced the next month. A second set of eyes the next month revealed the phone was out-of-sync with their system. The tech did some reprogramming (with the phone off). So far, so good. Thanks a million, Julie!!!
IF THE ABOVE STEPS DON'T WORK FOR YOU, try managing your apps from within a browser until such time as we have found the solution that works for you. We will write up how to do that and add a link here when it's ready for you.
STILL NOT WORKING?
