An unknown error has occurred (3194)

Hi,
I have an issuse with my iPhone 3Gs. The firmware of my iPhone was 4.2.1 and I updated it to (iOS 4.3) easily, but when I try to update it to (iOS 4.3.1) this message appears : "The iPhone "Bassim" could not be updated. An unknown error has occurred (3194)".
Any help?

Here is an article about this issue: Update and restore alert messages on iPhone, iPad, and iPod touch
The instructions for troubleshooting are quite extensive so it is better if you see them directly in there.

"The iPad ' ' could not be restored. An unknown error has occurred (3194)."

I work in quality assurance within my company, and we have a company iPad to perform testing on. This week, while trying to update to iOS 5, that error message would pop up. It suggests to update iTunes and make sure to be logged in as an administrator, which I am. I have done all that Apple has suggested, but still no luck.
Anyone have any other suggestions?

So:
I turned off firewall and magic happened! All is well with my iOS 5

HT201442 for my ipod 5g i can not downgrade ios 7.0.4 to ios 6.1.3 it was saying that (a unknown error has occured {3194} ,,,,can you help me too downgarde//

i want downgrade ios 7.0.4 to ios 6.1.3 it wsa saying that [error-3194] can you help me too downgarde

Thar is correct. Downgrading the iOS is not supported by Apple. If you try you will get the 3194 error.

HT201210 what is error 3194? i tried to restore it and it said the an unknown error has occured, error 3194.

i tried to restore it and it said the an unknown error has occured, error 3194.

3194 means that iTunes cannot contact the update server to verify the update. This can happen if the servers are being over loaded, or if the hosts file on your computer has been modified. HINT: This can also happen if your iPod was ever jail broken...

IPhone "could not be updated. An unknown error has occurred. (3194)"

So I have a Verizon iPhone 4 running iOS 4.2.7 iTunes has dowloaded 4.2.8, but when I tell it to update the iPhone, it starts and then tells me the iPhone "could not be updated. An unknown error has occurred. (3194)" Any thoughts? Thanks. Same thing happens with my iPad 3G, btw.

I keep getting the message "An unknown error has occurred" when trying to sign in to the App Store. Why?

I keep getting the message "An unknown error has occurred" when trying to sign in to the App Store. How do I solve this problem?

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

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?

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:
Detected use of SPRequest for previously closed SPWeb object. Please close SPWeb objects when you are done with all objects obtained from them, but not before. Stack trace:

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.

Ah not to worry i percievierd and managed to figure it out. Thanks to anyone that may have looked at my question!!

I got "Invalid link" when I to reset my security questions from rescue email. Moreover when I log in into my Apple ID and click on Passwords and Security I'm thrown out with the message "An unknown error has occurred".

Here is my problem:
Need to change my email with the one that currently I'm using for rescue
Planed to change first the rescue email with a new one.
But:
I Forgot the security questions
Followed the reset security questions instructions.
Got the email on the rescue address but The link I've got on my rescue email to reset my security questions is invalid. By now the 3 hour window for the validity of the link is gone.
If I go via Apple ID, I login successfully but when I select Security I'm thrown back into Manage your Apple ID screen that displays now as well this message "An unknown error has occurred"
Tried several times, the same again and again.
On top of the long hours on the forums I spent 20 minutes over the phone with the US support on international charge, eventually I hanged up while waiting too long for the 3 rd expert but got an email later on indicating to clear my browser history and try again, which didn't work. Case number 519598448. Used my laptop with IE and my iPad, same result.

This problem now appears for me too.
When using iforgot.apple.com email-verification clicking the reset link results in the "Invalid Link" error.
The error, that caused me to do this (password failing to verify against iCloud) has vanished since though.

Corrupted/Locked out apple ID "An Unknown Error has occurred" logging into support?

I was forced to use a different apple id to log into this support community because all attempts from different devices and browsers using another ID have ended up at the password prompt with "An unknown error has occurred" at the community login screen. The ID can still be "manged" and appears to be able to make purchases from the iTunes Store over the internet. A phone incident case number 388249960 was opened and I spent over an hour on the phone with this problem. The ID in question was set up more than two years ago to help with my wife's iPad 1 which we paid 800 plus for,,, all the storage and bells and whistles. Recently she started using the iTunes store to purchase and download television series and we got in trouble because her directories were filling the c:drive on a Vista Business computer she normally uses. Before starting to deal with the problem of storage, I tried to make sure everything was up to date and downloaded/installed the latest iTunes 11.0,1,, to her machine. I already had it on another machine running Windows 7 and two older Windows XP machines. All of them were "tested" for home networking to our Apple TV so that I could go to the TV and find a computer which could be used as a source for streaming music, videos, etc., etc. all based on her ID. As of this writing, I believe all of that functionality still exists, but, when I navigate to support and try to log in using her ID and password, I get re-prompted for the password and then "Locked Out" when "An Unknown Error Has Occurred" pops up above the login via the web site.
I am writing this after much agony and travial via an obsolete instance of Windows Explorer running on Windows XP Home Premium on an old portable using a newly created Apple ID which does not appear to have the same problems logging into the support community. Can anyone out there help me?
I have gone to war with Comcast's "free" security enhancement software "Constant Guard" believing that it might be the source. This machine had it installed at one time and has had it completely removed, but... it still experiences the error when my wife's ID is used.
The issue may be related to the recently added requirement for secuity questions and recovery email addresses which I tried to address for her ID and inadvertently ran into conflict/problem with using certain other email addresses with her ID. Perhaps something is corrupted in the database for her ID, or related to problems with support for esoteric things like Microsoft's .NET enhancements which I have long been using on my computers, or possibly Constant Guard "started" the problem because it was probably running when account security data was being updated via the Apple web site? I tried to get information about what I thought was the "recovery email address" associated with her account and was told by Apple Web sites that it was "in use" as an apple ID and could not be used as her recovery address. When I called trying to confirm that this ID was "mine" I was able to provide one of two security clearance pieces of data, but not enough information to get the support person to straighten things out for me. I ended up creating "yet another" ID just to get clear of the mess.
I made a suggestion to one of the folks I spoke with that an improvement to the functionality of apple ID's would be to support "consolidation" of accounts so that if several different Apple devices had been registered with different ID's and they all belonged to the same user(s) that a "common ID" could be created.
I'm reluctant to post apple ID's in a public support forum, and would prefer to deal with this by private email. or phone.

Then contact Apple directly.
This is a user to user technical support forum. No one here has access to manage Apple ID's other than their own.
There is no Apple presence here.
