Setting up Match or Genius: An unknown error occurred (-54).
New Macbook Air w/ Lion and iTunes 10.5.1.
Brand new iTunes, no media files or previous settings imported. Just signed up for iTunes match and while i was able to sign up (got charged) when I try to "Add this Computer" and sign in, I *instantly* get a pop up of: "We could not complete your iTunes Store request. An unknown error occurred (-54). There was an error in the iTunes store. Please try again later."
Initially I thought this was just a bug with launch, and waited until I got home and tried on my iMac... Here I was able to scan my library and get about 8500 songs into iTunes Match. Going back to the Macbook Air, same issues.
This has been over 48 hours of this now, and in the mean time I have:
1) Removed the entire iTunes directory from my home folder to create new configs.
2) Reinstalled 10.5.1 several times
3) Tried putting just one song into iTunes to see if there was an issue here
4) Ensured that OS has all available updates.
5) Ensured that App firewall in System Preferences is off.
6) Created a new profile all together.
7) Logged in with different iTunes account.
8) Verified that I can make socket connection with 80 and 443 to all listed Apple servers as seen at: http://support.apple.com/kb/ts3125
9) Tried from different networks.
Interestingly, this may not be related to only Match, as I am now finding that I cannot get Genius to turn on either.
The only additional point here is that this is a company image, however the company I work for has verified that there is nothing in the config that should be preventing iTunes from reaching out to any Apple servers or preventing this from working.
Anyone have any thoughts, or similar issues?
