Really bizarre. Hearing some people suggest that it's a problem on Apple's end is discouraging, as it suggests anything else I try may automatically fail. Yet if I can use the App Store from another user account, that suggests there has to be something lurking in my main account's Library (probably) that's causing the problem...
After running around in circles trying to get this resolved for me I finally found a (fairly easy) solution - the key point here is that the AppStore works just fine form another user account on the same computer (using the same AppleID) so it has to be something in ~/Library rather than /Library (thus ruling out the NetworkInterfaces.plist fix - which I tried and which didn't work for me).
Here is a step-by-step of what worked for me:
- Create a new user account - let's name it "Test" - I did not make this an administrator account
- Log into that new user account (skipping the AppleID/iCloud screen)
- Select "Software Update…" from the Apple menu - you will be asked to enter an administrator name and password in or to check for system updates - just provide your normal (admin-enabled) user name and password
- If you have any updates available, click "Update All" and log into the AppStore with your normal AppleID/password (this should work since you are in a new user account)
(If you don't have any updates available, I assume that you can also log in using the menu item in the Store menu of the AppStore application though I have not tried that) - As soon as the download starts, you can quite the AppStore application
- Log out of your test account and back into your normal account
- Open /Applications/Utilies/Terminal
- Type the following command:
sudo cp /Users/test/Library/Cookies/com.apple.appstore.plist Library/Cookies/ - Open the AppStore again and you should be able to log back in
What does this do? It seems that the com.apple.appstore.plist file in your normal user account has become corrupted - we use a new account and create a new one (which is interchangebale since we use the same AppleID) and move that one back to the main account with the corrupt file.

DNS was definitely NOT the issue for me. Entering Google's DNS (8.8.8.8 and 8.8.4.4) made the situation worse, not better.
NOTE TO APPLE: this is a clue stick for you. If your silly app is demanding for me to login but I cannot login because I am already logged in, then YOU HAVE A BUG. Please fix it.
Hi, I tried Kansie's solution below: adding two DNS addresses and clearing the cookies and that worked.
Thank you
This fixed the problem for me. Thanks a lot! 🙂
HELPFUL, Idk why I can't rate it anymore but this worked for me.
I got a handed down Macbook Pro from my older brother, and it kept bugging me why I can't update OS X to MacOS. It kept on asking me to sign in, but it just kept on giving me errors like "Unknown Error (4)" or something. Turns out my brother's account was still signed in to appstore and I kept on logging in mine. so there, signed him out and logged on to mine. Done! THANK YOU SO MUCH!!!
My network interfaces are ok. I tried to track down the App Store login process and discovered, that the following error message is written into my /var/log/system.log
Sep 16 01:52:13 MacBookPro.local App Store[40652]: [IMKInputSession deactivate] exception caught.
IMKInputSession:<IMKInputSession: 0x7f83392c0870> --
NSInvalidSendPortException : [NSMachPort sendBeforeDate:] destination port invalid
The NSMachPort class is used for distributed object connections on the local machine. Seems the login process has problem with interprocess communication.
It's still not working for me on 10.6 Mac Mini. I installed the latest iTunes update and rebooted.

I have just had success with this by deleting the auto-filled apple I'd, then retyping it in, then filling in the
password.

I have tried many of above solutions, but it's not work for me, i try to close all other app using internet and it's works. Keep your eye on Skype or similar app using port 80 & 443.
In the Apple Store app go to top menu item> "Store"> log out> then again log in with your account.
I had this problem for a long time but it fixed the issue for me.
