SKPaymentTransactionStateFailed "An unknown error has occurred" in sandbox testing but earlier the sandbox was working good!

Hi I am getting error as the case:SKPaymentTransactionStateFailed is being hit and its showning "An unknown error has occurred" although the sandbox was working earlier fine as the case:SKPaymentTransactionStatePurchased was being hit earlier, but today I have tried all possible ways to get the sandbox working but unable to make the sandbox working again. Is it due to fact that today apple server is down???

App store keeps coming up an unknown error has occurred when trying to purchase on the laptop

When trying to make a purchase on the app stroe on my laptop it keeps coming up with an error saying "an unknown error has occured" How can i fix this?

There are many forms of unknown errors. Was there anything else along with this mentioned?

The iPod "iPod" could not be restored. An unknown error has occurred (11).

I recieved an iPod from a friend of mine. He has bought a new one and is currently using it with his apple ID. I have plugged in the iPod he gave me and attempted to restore it. When it goes through most of the restoration process the error "The iPod "iPod" could not be restored. An unknown error has occurred (11)." pops up. The iPod is also stuck on a screen with a USB cord pointing twords the iTunes icon, i shut it off then turn back on and this image is still on the screen. The iPod also does not appear in MyComputer. It does appear in iTunes but it only has the name, no serial number, capacity, or software version. I also re-installed iTunes. I am using windows 7 on my Toshiba Satellite A665 laptop.
I would appreciate any help that anyone has to offer.
Thank you.

There was a problem downloading ... An unknown error has occured -42018...

Dear all,
After upgrading to i-tunes 7 I'm not able anymore to download music. If I run diagnostics everything seems fine.

However downloading the songs I bought doesn't work.
Following error:
"There was a problem downloading "...". An unknown error has occured (-42018). Please check that the connection to the network is active and try again."
But my network is active and the diagnostics turn out OK. Please help me out!! I have songs to be downloaded that I have already payed for.

This didn't work for me, but to any who may be interested, I also was experiencing unknown error -42018 when attempting to download purchased music. Additionally, I was stuck in an endless authorization loop when attempting to play previously purchaed music. All this started when I installed the latest iTunes software 7.0.2. But I managed to fix the problem on my machine.
I run windows XP Pro, and unlike the majority of users I actually set it up correctly with a dedicated administrator account, and regular user accounts instead of just running as admin all the time. For me, that was the cause of the problem.
The new version of iTunes software required FULL CONTROL privilages on the iTunes and iPod install directories for all user accounts that were using the program. (Previous versions worked fine, so this is a new thing.) Once I provided those permissions, iTunes worked correctly. Follow this link: http://support.microsoft.com/kb/304040 for information on how to provide FULL CONTROL to every user account.
I hope you all find this helpful in solving your problem.
Good Luck,
Bill

Make sure you have the correct country selected. Click the round flag icon bottom right side of the App Store window.

An unknown error has occurred when trying to sign in , and I know I putting in the correct info, this stinks can anyone help? Because apple isn't...

urgh... just noticed my previous post said i have mountain lion... i meant that i have snow leopard. no idea why i messed that up!
anyway, i just tried reinstalling snow leopard from the usb key that came with the computer. Then, I installed software updates until it told me there were no more updates. After that, I tried the app store again, and it still is giving me the unknown error. really irked by that. may have to take it back to the apple store yet again, to see if i can figure out why the app store won't work.

I rented a movie via Itunes on my PC but half-way through the download recieved a "An unknown error has occured (-50)" notification. This is not my first rental, and I have verified my network and all connections to be good. Will I still be charged?

I rented a movie via Itunes on my PC but half-way through the download recieved a "An unknown error has occured (-50)" notification. This is not my first rental, and I have verified my network and all connections to be good. I have rebooted Itunes and resumed the download of the movie only to receive the same error code. Has the movie file been corrupted? Can I recover the rental even though the time has elapsed? Will I be charged?

Did you figure this out? I haven't rented a movie in this new iTunes yet and saw one tonight I wanted to rent. Same fricken thing is happening to me. I hate this new iTunes, and I really hate that there are problems like this....why the heck do they have to fix something that isn't broken and break it? This just really stinks.

I can't connect with the App store. It says "An unknown error has occurred"

This just started a few days ago on my MacBook Pro. My account is working fine - I can access it on my phone. But I can't get to it on my computer.
The first sign of trouble was when I tried to use a previously purchase app. The app wouldn't open and gave me a message saying it wasn't purchased on this computer (which it was) and that I needed to enter my password. When I entered it, it said "An unknown error has occured". The first time it happened, I rebooted the machine and then the app opened and I was fine. Next day same problem. Our IT guy (not a real IT guy, I work for a small company and he is the most knowledgable about computer so he gets to do double duty) suggested making sure all software was up to date. I downloaded updates, the computer rebooted, and I was fine again. Day three comes and same problem. Rebooting didn't help. IT guy suggests upgrading to latest OS. But when I try to access the app store to get the new OS, it asks for my password, and then says "An unknown error has occurred". The computer can see my account. It has my ID right, and I have a credit balance which I just updated last night and is being properly reflected on the home page. But I can't buy anything or see details about my account. I keep getting the same pop-up.
Any idea what is happening or how to fix this?

On what OS?

I have searched the internet but most similar issues revolve around the resource center. I did find one person who just backed up the databases and provisioned a new site with success, but this has not worked. I am using the farm admin account, but all users
get this issue.
Any one got any ideas?

Bit further now.
It seems one of the project won't publish, and produces this error;

Anyone seen this? If I delete this project the project center loads. Obvisouly I don't want to do that though!

Project Server 2010 Task page - An unknown error has occurred

Hi All,
I have searched inside the forum for similar problems but i didn't find any solution.
We have Project Server 2010 with December CU installed and
we are
experiencing
a serious
problem with two enterprise resources.
They can login to pwa succesfully but when they enter in the Task page the following error is raised:
An unknown error has occurred
There are no errors reported in the event viewer while in the ULS Log I found only this entry but i don't know if it's related with this issue:

It's not a task related errors because i have alredy done an analysis of the resorce's assignments.
I have also verified IIS authentication settings as described in this
post but all had been alredy correctly configured.
We have a farm installation with two physical server:
Application Server with Windows 2008 R2, SharePoint 2010 Enterprise, Project Server 2010
Database Server with Windows 2008 R2 and SQL Server 2008 SP2
Any help would be greatly appreciated!
Thanks in advance.

Hi,
I faced exactly the same problem: some resources try to connect to My Tasks, and get an Unknown error. No error message in ULS or Eventlog.
I hope I solved the problem, and want to share the experience here.
First, by reading this article,
http://www.projectserverexperts.com/ProjectServerFAQKnowledgeBase/Unknown%20Error%20My%20Tasks%20Page.aspx: even if the SQL Query returns me no records, it gives me the idea to delete (unpublish) some tasks (i managed to identify some tasks which raised
the problem, by assigning a test account on them, and see that the pb happened).
So I decided to delete my project from the Published Database (and keep it in the Draft of course). Than in Project Pro, I opened and Published: the problem seem to be solved.
I don't know the root cause of the pb: maybe some SQL data were corrupted for an unknown reason.
Hope it could help some one ! Don't hesitate to give feedback if you solved this pb with this solution, or workaround.
Sylvain

SKPaymentTransactionStateFailed "An unknown error has occurred" in sandbox testing but earlier the sandbox was working good!
