    Basically, it means that either the link you have is bad or the Connect server you are trying to connect to is down or inaccessible.

  • TS1424 I am receiving error message -3212 when trying to access the iTunes Store.  Does anyone know what this means?

    Not sure what to do about the error message I am getting.  Also, my itunes is not recognizing my phone when I plug it in.

    Just in case, let's try the following document:
    Apple software on Windows: May see performance issues and blank iTunes Store
    (If there's a SpeedBit LSP showing up in Autoruns, it's usually best to just uninstall your SpeedBit Video Accelerator.)

  • HT203174 When I try to sync my iPhone to iTunes it gives me a message with the error (-54). Does anyone know what this means?

    I own an iPhone 5s, but this also seems to occur with any of the other devices I try to back up or sync.

    Something temporarily wrong with your internet connection?
    Be aware that this is a very large file to download, it needs a strong consistent internet connection.
    Have the iPhone on the charger cable too.
    In the meantime read the threads in this forum about the visibility item and some other possible issues on the 4 and 4S (although a large number of people have these issues, it is still a minor percentage, but anyhow, be aware).

  • TS3899 When I try to access my email it says the connection to server failed. Does anyone know what this means?

    I'm trying to access my email and it tells me it cannot access the server

    Lots of possibilities:
    The server is down (likely if it has worked up until now)
    You did not enter the server name correctly in setting it up
    You misspelled your login name
    The passcode you entered is incorrect
    The port you entered is not supported by the server
    The server requires SSL and you did not enable it
    The server does not support SSL and you DID enable it
    The network you are using is blocking access to email servers

    It usually means your OS has corrupted files. You need to reinstall OS X.
    If you are using Snow Leopard:
    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.
    If you are using Lion:
    Reinstalling Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Continue button.

    got your message about making sure to use the machine specific disk that came with my machine. Unfortunately, Apple no longer sells Tiger replacement disks. I've got a couple of bids out on ebay, and will update when I have news to add to this post.
    Thank you for your help, Frank!
    To be clear you called the 800 number and explained what the situation was, old machine and lost the original DVD's?
    Just checking because if you just called and tried to buy the DVD's they might tell you they no longer sell them but you aren't really trying to buy them your trying to replace the ones that are missing.
    Ebay may work but there is a certain specificity to the DVD's required which, even if they seem right, might not work.
    Good luck either way. If you get a chance when you get the DVD's I'd be interested in hearing how it all works out.

    l have an apple tv  2 generation please help me

    Welcome to the Apple Community.
    If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
    Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
    Connect the micro USB cable to the Apple TV and to your computer.
    Reconnect the power cable (only for Apple TV 3)
    Open iTunes.
    Select your Apple TV in the Devices list, and then click Restore.
    (You may already have a micro USB cable if you have a camera or other digital device)

  • After downloading the latest version of iTunes and updating my iPhone everytime I turn on my computer I get a message that reads: AppleSyncNotifier.exe - Entry Point Not Found. Does anybody know what this means?

    After downloading the latest version of iTunes and updating my iPhone, everytime I turn on my computer I receive a message that reads: "AppleSyncNotifier.exe - Entry Point Not Found. The procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library SQlite.dll" Help! Does anybody know what this means and how I can fix it? Thanks.

    Yes.  I just solved the problem on my PC.  Here goes...
    Issue:  My Windows7 computer was producing the pop up box with the error text as you described.
    The Problem: You have another application on your computer that uses the like named .DLL file... in this case a DLL supporting SQLite on your local PC.
    Solution: 
    1.  You need to use the Windows File search feature to look for the name "SQLite".  This will quickly locate the offending DLL in the other application.
    2. Decide which program you like the most, in my case "Mobile Me", and uninstall the offending application.
    3.  Uninstall Mobile Me.
    4.  Restart your PC.
    5.  Reinstall Mobile Me.
    6.  Mobile Me should sync at this point, but if not, restart the PC once again.
    In my case, the offending program was my Aptana Studio development application.  I had recently the SQLite3 database to my Ruby On Rails configuration...
    This is where the file was located:
    C:\Users\<USERNAME>\Aptana Studio 2.0\plugins\com.aptana.radrails.sqlite3.win32_3.5.7.1278709071\vendor\SQLite3.d ll
    I hope this helps,

    Means you have an incompatible Safari extension installed. Look in the /Home/Library/Safari/Extensions/ folder for the offending plug-in and delete it.

  • IPhone turns off often, turns back on only after reset, tried all troubleshooting and still nothing. Does anyone know what could be causing this and any ideas on how to fix it?

    My iPhone 4s shuts down at least once a day, usually after I used it or when I'm not using it at all. It will not turn back on unless I reset it (by pressing home/power buttons) and when it turns back on, it runs like nothing happened. I have tried everything I can think of, update iPhone software, iTunes software, troubleshoot on Apple's Support page and reading other user's issues but I haven't seen anything similar. I erased and restore factory settings several times, made different backup attempts and even restored from recovery mode with iTunes. Everything goes great, no error message or anything unusual, until phone is off again, very frustrating. It doesn't seem to have a pattern to it, it happened when no apps were running as well as when a few apps were. The only thing I can think of is I haven't seen this happening when charger cable is plugged it. I don't really care about apps and content on the phone, but my contacts and voicemails are the only reason why I absolutely have to restore from backup, even after setting up a new phone, from iTunes. Other than that phone is brand new, battery is also great, nothing wrong with it (apparently).
    I would like to know if somebody knows what this could be, and any ideas on how to fix it. Thank you.
