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 🙂

Happened to me just a few minutes ago and I thought I was gonna go crazy. =_= Adding open DNS address plus crazy refreshing worked on my machine:

Quit your browser.

Add the following to your existing DNS addresses (System Pref>Network>Your Connection>Advanced>DNS):

202.67.222.222
208.67.220.220

Launch your browser and if the page still doesn't load, just keep on refreshing. For me, it was a hit and miss connection for the first few minutes after adding the new DNS numbers. The connection eventually stabilized.

This is not a server problem.

This is a problem with OS X. Not sure which version, but definitely Leopard.

I've tried switching Networks, turning my WiFi off and on... to no avail.

It can happen on any random site. It happens a lot to me on localhost (127.0.0.1). So, even though I'm not going through WiFi (I'm accessing a server running on my own machine) I still get the problem.

But, the site is not the problem, it is the desktop OS. Rebooting the machine is the only sure way I've found to get rid of the problem.

This is a real pain in the butt. This is the 2nd time it's happened to me today (4th time in 2 days), and I'm losing productivity because of it.

I have the same problem every now and then with my blog. Sometimes it will knock all our Macs on my work network from being able to view it, other times it is just from my home network.

We just kept getting "server stopped responding" errors.

From discussions with my host, I found out the site was still there through megawebproxy.com.

I even had a kind person with my internet provider trying to help me on their own time when it happened once with no luck.

Luckily tonight (well not luckily) but I got the "kCFErrorDomainCFNetwork error 302" error and did a search for it and found this thread.

I tried turning off the TCP and then back on and it fixed the problem. So thank you to all for at least finding a work around until Apple figures this out.

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.

This error cropped up on our Mini, purchased less than 60 days ago. When the problem occurs, Safari and Firefox stop loading pages, Mail stops opening attachments, and the printer (hooked directly into the USB port, not accessed through the network) stops printing. The only way we have found to get everything working again is to completely restart.

I just got off the phone with Apple support and they completely passed the buck by saying it was our ISP's fault. I told them this didn't sound right because the USB-accessed printer stops working at the same time, but they just gave the rote response that it was an ISP error code and that they couldn't do anything. I asked them if they had any further information that I could provide to my ISP, and I got a very firm no. Sounds to me like this is an issue they're aware of and either don't want to/can't fix, and are therefore playing the blame game.

Does anyone have any advice on how to proceed? This computer belongs to the president of my firm and he is getting, understandably irritated with the whole thing. I hate to say this, but if we can't get it fixed I may have to switch him back to Windows, because at least on it you can open attachments and web pages!

I have not encountered this error until today and have been running Mac OS 10.5.5 since its automatic update, and similarly, running iTunes 8 (which is now 8.0.2) since its automatic update.

The thing that has changed, however, is I just added an iPhone 3G to the mix this past week.

So far, I'm only getting the error on one site that I use somewhat frequently, which is a file hosting/sharing site.

Hi

I just started to get the 302 error 2 days ago. It only occurs when trying to view my own website which I hand coded - http://westcumbriaphotogroup.co.uk/ It occurs intermittently on my Intel Macbook Pro running Safari 3.2.1. On my windows PC running XP service pack 2, I get the same problem using either Firefox or IE, except that I just get a blank page. I asked friends using their PC's at home to try to access my website, and they had the same problem. None of us has any problem whatsoever accessing any other site.

Reading through this thread, opinion seems to be that it is not a server problem. I have spoken to my hosting site support team who can replicate the problem in Firefox and IE, but can find no problem with their server.

I have not changed anything either with my website, or on my computers, and this 302 problem just decided to start happening.

I cannot understand how this is an OS X problem, when being able to replicate the problem with other OS's. To be honest, I am completely baffled by it.

Just thought this information might be useful, and hoping someone can fix it.

Thanks
Graeme

Well, not only is it happening to me, but I'm receiving reports that this is happening all across the campus I work at.

Lets see if this gets Apples attention.

I am the Lead Web Developer for Intranet Applications at a university that purchases a 15 inch Mac Book Pro for every incoming student...

Ok, now that they're paying attention...

A web server/application that I administrate is reporting the kcfErrorDomainCFNetwork Error as mentioned in the opening post when using Safari.

I have one faculty member who emailed me about it tonight with the problem.

The server is not under heavy load (I'm the root admin and can check such things), none of the drives are full (to possibly indicate apache can't write to any logs).

I've confirmed with another coworker that Safari is having this problem (version: 3.1.2)

I am running safari 3.2, and I'm on 10.5.5

I am now going to run the updates on my laptop to safari 3.2.1 and OSX 10.5.6 and see if that fixes things.

A larger concern to me is that all of the computers that my employer provides to students and faculty are on a locked image, and are not easily updated en mass by us at this point.

If an apple dev/rep could comment and let us know what the best course of action is, it would be greatly appreciated.

Thank you.
