Ipod no longer authorized (unknown error -42408)

posted this at itunes site as well.
out of blue, having problem i've never had syncing my 60G ipod.
for years have been syncing this ipod with my itunes on my macbook (only). for the past few times (?month or so), i'm getting an error message when i try to sync that first says, the ipod/macbook is not authorized for this ipod (which it always has been).
then it asks me if i want to authorize it. when i hit "authorize", it brings up an old itunes account i had and asks me for the old password, which i enter. then i get an error message that says:
"unknown error -42408. error in itunes store. please try again later."
how do i fix this so that i don't get this error message and can continue syncing with my most recent account, which has NEVER been a problem in the past?
thanks.

I have exactly the same problem. My iPod is a 30GB one from 2005 or 2006 (I don't know how to identify its category). When it was new, I had a PC; then a year and a half ago I switched to a Mac and got everything transferred ok, and have been synching the iPod to the Mac with no trouble since then. (Well, slight trouble, because the iPod is now very full, and I haven't figured out the best way to synch "almost everything", but so far I'm managing somehow.) But just before leaving Moscow March 10, I wanted to synch and recharge the iPod, and got the same problem, with the same sequence of messages described at the start of this thread. So I only recharged it. Now I'm in Amherst, tried again, exact same problem. So now only recharging again.
Same computer, same iPod, why does it suddenly not recognize that this computer is authorized to synch this iPod, and why does it make this error when I tell it to authorize it? And how can I fix it?
Grateful for any help.
Barbara

IPod cannot be updated Unknown error-48

Help - have installed iTunes 7.0.1 and am trying to keep ALL the music on my iPod so have tried to set the options to manual update. But although the computer senses the iPod is connected, when I try and drag new files to my iPod, I get the message "iPod cannot be updated Unknown error-48" Any advice gratefully received

Hey!
Just an update since last week.
Still comes up with the "Unknown Error_48" when coupled to the Mac.Doesn't sync to iTunes and says it's upto date in the summary.Never had any issues like this (until iTunes 7 and 1.2).Kinda renders the whole iPod thing a bit useless.
Being able to update the library on your Pod is essential.Otherwise what's the point?My Pod still 'works'but not quite the way Apple intended I think.
SORT IT OUT APPLE!!

TS3833 I am receiving this error when syncing my ipod: iTunes could not copy "song name" to the iPod "name" because an unknown error occurred (-50). I am using iTunes version 10.6.3.25. Why?

I am receiving this error when syncing my ipod: iTunes could not copy "song name" to the iPod "name" because an unknown error occurred (-50). I am using iTunes version 10.6.3.25. Why?

Right click the filename that won't download and selsct 'Get Info'. Look at the file path, does it have a //?// in it? That is a problem with Amazon downloads that prevent iTunes from finding the file. Use 'Add Folder' to add the album to your library and try syncing it again

An unknown error (-42408)

Cannot connect to the iTunes Store because of an unknown error (-42408)

Hi
I know this thread is a little old but I thought I would leave the solution I found that worked for me. I'm on a mac mountain lion.
I tried uninstalling reinstalling and that didn't work.
You may want to back these folders up before trying this.
1) Quit iTunes.
2) Go to System/Library/PrivateFrameworks/
3) COPY the following folders to a different location just in case
AirTrafficHost.framework
CoreFP.framework
DeviceLink.framework
iTunesAccess.framework
MobileDevice.framework
4) Delete them from the original location.
5) reinstall iTunes
6) Smile no more error -42408

Hello suesq75,

Itunes could not copy 'song' to the ipod 'name ipod' because of an unknown error occurred (-5000)

Itunes could not copy 'song' to the ipod 'name ipod' because of an unknown error occurred (-5000)

This problem does seem pretty random, affecting just a small number of tracks. Apparently it is due to some file corruption or something... Anyway, this thread https://discussions.apple.com/thread/2654317?start=15&tstart=0 has a couple of solutions spelled out. Basically the same thing that a-monk-at-large suggested above. (Delete and redownload the offending tracks.)

Authorized computer Error 42408

I have an Ipod Nano 2nd Gen everything has been working find until recently. iTunes said this computer was no longer authorized to play purchased items...It also has a very old email address listed that I no longer use. I login just fine and authorized the computer. I read on that if you de-authorize the computer restart and authorize again it should solve the problem but I should not have to to this everytime. I also went to the apple website and checked to make sure that my information was correct.
Today I received the same authorization and when I try to sign into itunes I receive this error: we could not complete your itunes store request -42408.
Does anyone have any ideas? Thanks for your help.

I had a similar problem, so I emailed iTunes Store and asked them what they were going to do about me not being able to play the music they sold me on their software.
The following fix worked for me, sent by email from iTunes Store Support:
I'm sorry to hear that you have been experiencing difficulties with the iTunes application and are receiving error 42404. My name is Gerri, from your iTunes Store Customer Support Team. I know that you are looking forward to having this addressed as soon as possible and I'll be happy to assist you today.
To resolve this, I recommend uninstalling and reinstalling iTunes. Before beginning, please back up your iTunes library as explained here:
How to back up your media in iTunes
http://support.apple.com/kb/HT1382
To uninstall iTunes, please follow the steps in this article:
Removing iTunes for Mac OS X
http://support.apple.com/kb/HT1224
After you've uninstalled iTunes and removed the related files, you will need to reinstall it. You can download the latest version free of charge from the iTunes website:
http://www.itunes.com/download
After you've reinstalled iTunes, please ensure you have the latest version of QuickTime installed. You can find the latest version here:
http://www.apple.com/quicktime/download
Please reply to this email to let me know how you make out and if you require any further assistance with this, as I would be more than happy to help you resolve it. My hours are listed below for your convenience.
Thank you very much for being part of the iTunes Store family.
Even though I followed step 1 (backing up to disc), I don't think it was necessary, as all my music library and playlists etc remained intact. Eight hours burning DVDs for no real reason... Still, at least it's a fix.

Could not copy song to Ipod Touch due to unknown error (-50)

I just received a new third generation Ipod Touch as a gift and installed the latest iTunes directly from Apple's website onto my computer (Windows 7 32-bit). I added my music folder to the library and imported an m3u playlist to iTunes. Then I connected my iTouch, followed the instructions to set it up, and then I wanted to sync my songs to my iTouch. I only wanted to sync the songs on my "Favorites" playlist that I imported, so under the Music sync settings, I selected the option to only sync selected songs, playlists, etc. and selected the Favorites playlist.
Then I attempted to sync the songs, but only a few songs would sync before an error popped up saying that it could not copy a specific song to the device due to an unknown error (-50). This error sometimes repeats for multiple songs and then the syncing stops. Each time I try to sync it again, it might sync a few more songs, but will always be interrupted by the error, after which it stops syncing. These songs are MP3 files. I have already tried uninstalling and reinstalling iTunes.
This is extremely frustrating and I don't know what to do. Thank you in advance for any help you can provide.

I've managed to fix the problem and discovered the reason for it. When I dragged the playlist to the iTouch section in my iTunes (instead of pressing the "Sync" button) to sync the playlist to my device, it synced everything except for the handful of songs that were giving me errors. Then the error messages it displayed were more helpful in indicating what the problem was. They could not locate the song in the playlist on my computer because I had changed the MP3 tags a long time ago, sometime after I added them to the playlist, and it never updated. (Note: the playlist I was syncing was originally made in Zune player and then I saved it as m3u format) Hope this helps someone with a similar problem in the future.

Cannot connect to the iTunes Store because of an unknown error (-42408)

Sometime - like about 3 times a week - when i sync my Ipod with itunes 9.0.3, I get a message saying that I am not authorised to play some songs on my iPod. I then have to authorise my computer for a previous apple ID. Usually, this authorisation fails with an error code 42408 when iTunes tries to connect to the iTunes store. I am using the correct (old) apple id and the correct password but get the message "we could not complete your iTunes stores request. An unknown error occurred (-42408)"
Can anyone shed any light on this and let me know what the solution is?
Thanks

Thanks. Option 1 worked for me:
1. Eject and disconnect the iPod/iPhone from the computer.
2. Open iTunes.
3. Find a protected song from the iTunes Store (Kind = Protected AAC audio file) in your library.
4. Play the song.
5. Connect your iPod/iPhone.
I hope Apple fix this soon - it's very irritating!

IPod no longer Authorized, since OS 4.3 upgrade

A little bit of history first- iPod touch is 1 year old (3rd gen). Until a week ago, I have had no problems syncing it with iTunes. All of a sudden, after the iOS 4.3 upgrade, next time I connected for Sync, I get:
This computer is no longer authorized for apps that are installed on the iPod "Jeff's iPod Touch". Would you like to authorize this computer for items purchased from the iTunes Store?
When I click Authorize, it prompts me for my account password. Then it tells me this computer is already Authorized. Later, rinse, repeat. It just loops between "Not authorized" and "Already authorized". I have tried to deauthorize the computer and reauthorize it, but that does not help.
Interestingly, my iPhone 4 does not have this problem- it is limited to the iPod Touch only (don't ask why I use two devices- I just do at this point in time).
The only other thing to change was the that I installed a small batch of Windows Updates also just before this happened, but the iOS 4.3 and that both occurred between the last successful sync and this problem.
I can seemingly get the data backed off the device (I think) but can't get past the app sync, and the only way out is to cancel, which leaves the music not synced either (playlists are getting stale now).
I was able to update the iPod Touch to iOS 4.3.1 update and the apps are still there, along with the music. I can use the device, I just cannot sync it anymore.
I also have latest iTunes- 10.2.2.1.
Help!
Thanks,
Jeff

Forgot to mention that I had tried those:
Authorize your purchases from an administrator account
-> Yep, I'm the admin
Authorize using the correct account name
-> Nothing changed- I am only authorizing my devices, and only use my account on the machine. Definitely using the right account name.
Turn Off User Account Controls (Windows Vista and Windows 7 Only)
-> Did this a long, long time ago, so definitely not the issue.
Remove the SC Info folder
-> This was the only new thing that I had seen yesterday when I tried it, and went through these steps, to no avail. Still exactly the same problem. I closed iTunes, deleted the folder, rebooted and relaunched iTunes and synced the device. Same thing.
The problem is the computer IS authorized, and I can sync one device, but not the other. No problem with iPhone 4- just iPod Touch, 3rd gen. It seems to be in a weird state.
One thing would lead me to believe it's a PC/iTunes problem, but then it is only with one device and not the other. Hard to point to the root of the problem. I just don't want to lose the data on the iPod- I've done a lot of work on it.
Thanks,
Jeff

No matter what I do I cannot restore ipod classic. Ipod is corrupt with unknown error 1439.cannot restore the ipod Have tried all options but . can anyone help?

I recently bought a second-hand ipod classic. When connecting to itunes the message reads that the ipod is corrupt and needs to be restored to factory settings. However, this does not solve the issue and I get the message saying unable to restore, unknown error 1439. No matter what i have tried through apple support i get the same result. My computer runs Windows XP but I have also tried on my laptop which operates Vista and still no joy. Anyone able to solve this one?

Normally unknown error is due to timeout, cause by
connected to slow USB port at the front of the PC, or using USB Hubs - Better connect to the USB HUb at the back of the PC. (Some Laptop, has only one High Power -USB2.0 port
USB resource low, due to sharing of other USB devices - Disconnect all other USB devices when Restoring.
Winsocks conflict with iTunes - Disconnect Internet and Stop firewall and Antivirus, emails apps.
Your hardisk is dying, read this earlier post by tt2.

This wont solve your problem. but is very helpful in troubleshooting.
It would also help, if you can state
Which version of iTunes are your running?
What is your iPod software version as shown in the iTunes summary page?
Have a nice day!
