KCFErrorDomainCFNetwork error 302 - Meaning and fix?

Hi everybody,
I am getting random error messages called "kCFErrorDomainCFNetwork error 302" in Safari every now and then.
To me, this looks like a problem either resolving the URL or a timeout while waiting for a page (since it takes time for Safari to come back with the error after a page was requested). The message is not related to a specific domain or page. Hitting reload eventually brings up the page.
I have searched the forum but was not able to find a definite answer. Does this have something to do with HTTP Error 302? Any ideas?
Best Regards, Matthias

I get them toooooooo.
And it's not Safari only issue. Firefox gives me some different message but refuses to open a page also.
Restart helps sometimes but not for long. It seems there're a lot of people running Leopard getting these errors for some time already!!!
What I can't understand is why Apple doing nothing about it... Looks like downgrading to Tiger is the only option at the moment If it's true...
More upsetting is that this problem doesn't exist in windoze world.

KCFErrorDomainCFNetwork error 302

Yes -- the dreaded kCFErrorDomainCFNetwork error 302 message rears it's ugly head again. I've done searches and I've seen the posts in the Apple Discussions, but they are all in iPhone related forums, and quite frankly I think this is a Mac OS X Leopard problem, perhaps introduced with the iPhone 3G.
In my case: I have the problem from time to time, but most recently when requesting http://www.mmo-champion.com from both Safari 3.1.2 and Firefox 3.0.1 on Mac OS X 10.5.5. This worked fine before, but not sure what changed (and when) that caused it not to work any more. I can access other sites just fine.
I'm set up with O2 Broadband in the UK, and am using a double-NAT network solution to get to the internet (Public -> O2 Router -> AirPort Extreme -> laptop) and I don't have problems with other sites. I've tried restarting the network router (both soft and hard restarts) but it makes no difference. Could it be the web site? Maybe. I mean, I also have a Windows PC that can access the sites just fine on the same network... but perhaps the web site is doing something to offend Mac OS X, because other web sites work just fine.
Google search yields little help, which surprises me given the incredible number of folks that have this problem with blog-related sites, both on the iPhone and in laptops/desktops. With this much reporting, Apple should have at least recognized there's an issue.
So, to recap: I use Leopard, own an iPhone 3G and have iTunes 8 and iPhone 2.1 software installed. I cannot get to certain sites, with mmo-champion.com being the latest exhibit. The error I get, after a long time waiting (~120 seconds) is:
"Safari can’t open the page “http://mmo-champion.com/”. The error was: “Operation could not be completed. (kCFErrorDomainCFNetwork error 302.)” (kCFErrorDomainCFNetwork:302) Please choose Report Bugs to Apple from the Safari menu, note the error number, and describe what you did before you saw this message."
Firefox reports something similar, but not the same exact error.
Any opinions would be well received.
Thanks,
Daniel
Edit: I didn't mean to sound arrogant or condescending; if I came across that way, my apologies. I'm more interested in the details of the problem, as opposed to seeking its solution. I just want to understand what's happening. And I think the PDF that explains these errors is lacking of the kind of details I seek. If someone knows what's going on, I'd love to read about it. While I have my Windows PC I'll be able to get my WoW news just fine

This is definitely a problem with the operating system. There are 2 macs in my house and 2 PCs. The problem never manifests on the PCs, so that validates it is not a problem with the network. Of the 2 macs in the house, the laptop is at the latest level and the desktop at an earlier version of OS X (my appologies here - I'm a UNIX/PC guy and just throwing info up that I've noticed to help my girlfriend). Both of the macs are wireless, but only the laptop exhibits the issue. This indicates that is is specific to the system.
The commonality between the laptop showing the problem here and other users is the operating system. This isn't a problem with any specific website, router, or hardware (that I'm aware of).
I dropped down to the command line and threw out a quick test. A simple ping to www.google.com form the affected mac laptop and a PC laptop. The PC had no issues, but the mac showed not only large return times for the packets, but packet loss. So, the error that is popping up would be shown by busy servers but, in this case it is an "incorrect" error code. They symptom and error code together make sense, but it is wrong.
The source of the long return times and significant packet loss is beyond me at this point. Rebooting the system seems to resolve the problem for a while but the problem creeps back up.
These are my observations. I don't have a solution yet and likely won't, but I'll continue to research and post any findings here. This is a software bug (as upgraded systems suddenly have the problem) and I'm hope the proper resolution is provided soon.

What does this error message mean and how do I solve it? "Sorry, one or more of the following command-line tools was not found: /usr/bin/lsbom, /bin/pax, /bin/mkdir, /bin/chmod, or /usr/bin/update_prebinding."

When I try to open up this program, Pacifist, I receive this error message. Here's a screenshot. http://i.imgur.com/v717w.jpg What does this error message mean and how do I solve it?

It sounds like some of the Unix Executable commands were removed (or the permissions to those were modified) out of the /usr/bin/ folder. You can try opening disk utility and repairing permissions on Macintosh HD or you can reboot your computer and holding down option-r when it comes back up to reinstall Lion again. This will not delete your personal information or applications you have installed but it would be best to back it up to Time Machine before you do. The article on how to do this is here. (http://www.apple.com/macosx/recovery/) I have had to do this before and it works like a charm. It should fix your issue but grab a cup of coffee because its going to take about 35 - 40 minutes depending on how fast your computer is.

KCFErrorDomainCFNetwork error 302 Solutions

Hi,
Has anyone found a solution to kCFErrorDomainCFNetwork error 302 error message.

I'm also having this problem trying to access http://www.mmo-chamption.com from both Safari 3.1.2 and Firefox 3.0.1 on Mac OS X 10.5.5. This worked fine before, but not sure what changed (and when) that caused it not to work any more. I can access other sites just fine.
I'm set up with O2 Broadband in the UK, and am using a double-NAT network solution to get to the internet (Public -> O2 Router -> AirPort Extreme -> laptop) and I don't have problems with other sites.
Google search yields little help. I'm surprised Apple hasn't pin-pointed the problem. It's clearly with Mac OS X and some variable on the host site. I also have a Windows PC that can access the sites just fine on the same network. So I don't think it's my network. I have some complex port forwarding that works on my network, so it's design should not be a factor.
Edit: I use Leopard, own an iPhone 3G and have iTunes 8 and iPhone 2.1 software installed. Could this be the common denominator beyond 'Mac OS X' ?

What does the xantrex driver error 5 mean and how to solve it?

Dear Experts,
I downloaded a new XANTREX driver and used it to control our new XHR
150-7 power supply. I tried to use the GET STRAT.vi to control the
output of the power supply. The output could be controlled according to
the command input. However, there is always an ERROR 5 message poped
out whenever it ran. The error source seemed to be in the DELAY &
READ.vi.
I would be most grateful if you could tell me how solve this problem at your earliest convenience.
Thanks a lot for your attention and help,
James

Exactly which driver did you downlaod and from where? By "GET STRAT", do you mean one of the Getting Started VIs? Error 5 means "NI-488: Command requires GPIB Controller to be System Controller." Are you using GPIB to control the instrument? If so, what type of board are you using and which version of VISA and NI-488? If the error only occurs on a read, try issuing the query from MAX and see if the error occurs there. In a couple of the Xantrex drivers I looked at, there seemed to be some fixed delays after a write and before a read. You might try increasing those values to see if that makes any difference.

Error -1073807300 causes and fixes

Of four identically stations one commonly throws this error during one of several CVI compiled functions. This indicates a memory problem (windows?) or can this actually be an instrument problem? What are the common causes and fixes for this error?

Hello Ganrim,
You do not mention which kind of operations you are doing when you get this error. I assume you are communicating with an instrument using VISA (or IVI?) since the error seems to be related to VISA. What is the instrument you are talking to? When exactly do you get this error?
Actually, you should try posting this question (providing the answers to my questions, as well as the versions of all the software you are using -VISA, CVI and so on) in one of the Instrument Connectivity Discussion Forums (there is one for Serial Interfaces, one for GPIB, one for VISA and one for Instrument Drivers/IVI). That would be a more suitable p
lace for this question since this error is Not related to TestStand.

What does this error message mean and how do I fix the problem? Service "Apple Mobile Device' failed to start. Verify that you have sufficient privileges to start system services. I'm trying to install the new version of iTunes.

When I get to the service section when I try to install the newest version of iTunes I get an error message. I'd really like to be able to connect to the Apple Store but can't figure out how to get those "sufficient privileges to start system services" and there doesn't seem to be any help on the Apple Support section of their Website - at least that I can find. Can anyone help me?
I uninstalled the older version of iTunes. Apparently there was a .dll missing. I also uninstalled Safari since iTunes apparently uses some of the same applications as iTunes. It's getting frustrating not being able to buy books or access the books I already have.
Thanks for any help you can provide. Sometimes computers mystify me.

I am having this same problem. I took Kappy advice on restarting the Apple Mobile Device Service, however that did not work. I got this message in a pop up window that came up immediately.
Windows could not start the Apple Mobil Device Service on local computer.
Error 1053 The service did not respond to the start or control request in a timely fashion.
I have already uninstalled itunes, all the related programs and I cannot reinstall, this Apple Mobil Device message stops the install.
Can anyone please help?

WHAT DOES THIS HOT SYNC ERROR MESSAGE MEAN AND HOW CAN I FIX THE PROBLEM??

"THE HOT SYNC OPERATION WAS INTERRUPTED. SOME OF YOUR DATA WAS NOT BACKED UP."
"(ERROR: EASNotify.dll failed a confirmation query and cancelled the sync operation).
HotSync Error: An application cancelled synchronization or failed to respond to a HotSync notification. Please ensure that you are not currently editing data using applications such as Palm OS Desktop of Install Tool. (8009)"
I have spent hours upon hours trying to figure out what is wrong and why I cannot complete a hot sync with my computer. I have done a hard reset and reinstalled the palm desktop software numerous times with no luck. I bought a book on the palm. No mention in the book about this particular problem.
Can anyone out there help me with this problem??? I would be forever grateful!!

Post relates to: Palm TX

To check which applications are installed on your palm, you can click on the home button on your palm and make sure it says "all" on the top right of your screen. This will show you all the apps installed on your palm. Look through all the applications listed there and see if there is anything extra. You can list them here and I will tell you if there is anything that didnt come with your device when you purchased it.
You will not need the palm cd to reinstall everything again after you do a hard reset because all the info will be backed up on your computer from your sync. You stated that all the information is on your computer after you sync'd so you dont have to worry about losing it. Once you sync again after performing the hard reset, you will be able to get all the info back again on your palm.

What does error (-34) mean and how do I fix it?

I updated my iPhone 4 to iOS5 yesterday, but was told there was an error that occurred during the restore (-34, to be specific). I also noticed now that I've been browsing the forum that my music and videos are missing. The biggest issue I'm having is not being able to adjust settings when connected to the computer because it keeps prompting me to restore to a previous state, despite having done so twice now. Any help would be greatly appreciated.

Hi there I've just installed CS4 Pro on Windows 7 64bit and got exactly the same result as you. Did you manage to find anything out, because the thing that bothered me was the limited functionality (what ever that is). Is it just a case of Windows 7 having a newer version of ActiveX already installed?

What does this error message mean and what can I do about it?

I have a similar problem to others using Time Machine with Lion. I recently upgraded to Lion 10.7.3, but am now unable to get Time Machine to back up, despite reinstalling, verifying and repairing (unnecessary) my various internal HDDs. I realise that indexing takes some time but 14 hours overnight with no progress seems to indicate that something is radically wrong!! The only TM message is "Preparing Backup" and "Calculating" and the widget just tells me that standard backup has started. It never changes.
System log shows the following message:

If this file is corrupt, how can I remove it and replace it, or otherwise identify and correct the problem that
is causing TM to hang. Any and all expert advice welcomed.

What does error 261 mean and why does iTunes backup fail in version 7.3?

I made a backup of my purchased music (all single items) in the previous version of iTunes for Windows. Now with version 7.3 for Windows I keep getting error 261:
After inserting a blank CDRW, CDR, or DVD+RW (all previously without any problems in older iTunes versions) and selecting File -> Back Up to Disc, iTunes says: "Checking items for backup..." after which it shortly says: "Burning Disc... Initializing"
To abrubtly end with: The attempt to burn a disc failed. An unknown error occurred (261).
I used various burning options, including AUDIO and DATA CD, to no avail. The differences with my previous backup are:
- more tracks;
- complete albums;
- DRM free items (upgraded);
- audiobooks.
Although my main iPod contains the complete library (luckily it is small), I can use it for backup purposes, but after re-installing Windows and iTunes, my iPod would not be recognised and my data would be lost.
Shuttle SB83G5 Windows XP Pro

You are not doing anything wrong. This and many other errors have cropped up since version 7.3 was released.
For now, the solution is to go back to version 7.2 where everything worked correctly.
E-mail me at [email protected] and I will gladly share the steps I took with you. Apple does not allow posting a link to a site that they do not operate and therefore I can only help you privately.
My Itunes is working perfectly again with version 7.2
