NSURLErrorDomain error -1100 in Mountain Lion

Checking software updates in the Mac app store on iMac using Mountain Lion and just now getting my first error. Can someone tell me why? and how to fix? Could it be the server is down since they just annouced today the new iPhone, iPods?

iMac, OS X Mountain Lion (10.8.1)

I've no solution to propose, but given that I'm also experiencing the (NSURLErrorDomain error -1100.) error message, I wanted to add my voice here to those asking for a speedy fix from Apple. I've been a Mac user for many years, but this and other recent minor issues have me wondering whether Apple is losing its grip ever so slowly on its previously unassailable reputation for reliability...

I would echo your sentiment. Apple's software used to just work. Not so much anymore, although in fairness to Apple, this appears to have been a server side issue on their end rather than a software issue. Still, if you are going to market a tightly integrated user environment as Apple is doing, you had better make sure all your components work. And when they don't, you had better fix whatever is broken PDQ, which didn't happen in this instance. Otherwise, your "ease of use" edge you are touting disappears.

NSUrl can be used to open a number of different connections to a number of different things. It is not a DNS Error as two computers configured the same do not respond the same. Whatever the case, the problem seems to be growing, not resolving. It will be curious to find out just what it actually proves to be.

Software Update works like it should again!


@Doc Maynard: at first, I responded to your message quoted above, that NSURLErrorDomain code 1100 was to mean that a file did not exist. That is a fact, and I can show the evidence for it now, by guiding you to the following link:


https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundatio n/Miscellaneous/Foundation_Constants/Reference/reference.html


If you'd then scroll down to URL Loading System Errors (about one third down), it reads:


These values are returned as the error code property of an

NSError
object with the domain “NSURLErrorDomain”.


You'll then see a number of possible values. If you search the list for value "-1100", you'll find it means NSURLErrorFileDoesNotExist. There you go. At least now you know where I'd got my information from.


The fact that this specific error was returned, could be because of SUAppStoreUpdateControler being unable to download the file it needed at that time from Apple's server.
