We could not complete your iTunes Store request. The network connection could not be established.

I had the same problem these few days, but today I have found the solution. Just follow these steps because it works for me. I am not sure if it's going to work for you, but you should try:

1. Open iTunes.
2. On Mac OS X: From the iTunes menu, choose Preferences.
3. On Windows PC: From the Edit menu, choose Preferences.
4. Click the Parental Controls tab.
5. Place a checkmark next to the option to disable the iTunes Store, and next to the option to Allow access to iTunes U
6. Click OK.
7. Open iTunes preferences again.
8. Choose the Parental Controls tab.
9. Remove the checkmark next to the option to disable the iTunes Store.
10. Click OK.
11. Test the issue.

If resolved, it is possible the issue may return in the future. Look for updates to this article or apply future iTunes software updates for a permanent resolution.

Good luck,

I didn't do anything since my last post on the 1st page, except wait a few hours and log out and back into Windows and it seems to be working fine now. I'm guessing there was an issue with the iTunes servers?

Wish this was out here last night....I had the same problem around 2100 eastern. I searched and didn't find anything out there...I actually uninstalled iTunes and reinstalled on my pc. Our pc has multiple accounts on it, so I tried everything I could think of...After the reinstall, my account was still doing same thing with that -50 error. I logged into my wifes on the machine and fired up iTunes and got some other weird error...Still couldn't sign into itunes under her account either... I gave up... I guess I'll try it again tonight when i get home.. I just hope iTunes didn't mess up anything on the other user accounts on the machine...stupid itunes...

Disable iTunes Store in Parental Controls

Exit iTunes

Launch iTunes, notice you cannot log into iTunes Store

Exit iTunes

Launch iTunes, enable iTunes Store in Parental Controls

Exit iTunes

Launch iTunes and log into iTunes Store.

This did the trick.

Same error here for the past few hours, what's going on Apple ? 😟

Parental Access Control sulution. Solved my issue. Thank you.

Try to open the itunes store by your own first, then plug your iDevice to the computer, and that just worked to me 😀 😀 😀 😁

The Itunes U option worked for me as well.

I'm getting the same error messages. I guess maybe an issue with Itunes? I believe others on facebook are reporting the same issue. I've got a new iphone and trying to add apps and games and getting the same errors you are.

I'm also getting this. Apple shows iTunes Store status is normal, I'm getting the error messages at launch, can't sign in, can't re-download a song I purchased earlier. Deleted the SC Info folder and checked for updates, but still getting the messages. Kinda glad to see it's not just me.

Been having this trouble all evening. I use iTunes Match at work so I can leave my external hard drive at home. As a guitar teacher, I rely on it for work. It's mildly comforting to see that others are experiencing this issue and that it's not a problem with my Macbook Pro. I hope Apple fixes this soon!

The Parental Control toggle didn't work for me.

Still keep getting the arrow.

Was able to buy an album on my iPhone just fine, downloaded it just fine too, but can't see the music on iTunes on my PC, nor buy anything on iTunes on the PC.

Thanks for the post singerish. I just tried it, but no go here. I just upgraded to iTunes 11.0.2 on Mountain Lion 10.8.2 and started receiving this error about not being able to connect to the iTunes Stolre.

I first had "An unknown error...(-3212)". Then the ones you all show. I just happened to have a Win 8 Update and finally updated to iTunes 11.0.2.26 tonight so I have been messing with firewalls and reviewing all of the itty bitty details of both based on the useless support docs.

I'm just going to hang it up for another day. Sorry all of you are having problems too.

I tried the parental control and tried signing out and back in again, neither worked and I can't sign into my iTunes now. Hopefully this will be fixed by morning...sorry to all that are having the same issue. At least it can be safe to assume that it's not our systems but something on Apple's servers that is the issue.
