Cannot connect to iTunes match an unknown error 4001

Question

when i try to connect itunes match return an unknow error 4001, why?

Answer 1

I have managed to get iTunes Match working on my system by doing the following steps.
1. Click on the store tab and select "Turn off Itunes Match"
2. Did step one and selected "Turn on Itunes Match"
3, Selected Itunes Match and clicked Add machine button that is at the bottem of the screen, and then logged in with my Itunes account
4. The error would then appear again (error 4001) before step 1 could be completed
5. Went onto my itunes music where a cloud symbol has appeared next to each track in the cloud columb. At the top of the columb menu's i have clicked the cloud symbol which organises each track into the tracks that are eligible and ineligible (this included tracks that were missing on my hard drive)
I then removed all the track that were ineligible leaving me with tracks that were elidgible
Then went back onto Itunes Match and began the 3 steps to match my music with the cloud, i was then able to get past step 1,2 and 3 and was able to match my music.
This worked for me, im not sure if its a complete fix accross the board but it allowed be to get around the errors that were appearing.
Hope this works for the rest of you
**Edit**
forgot to mention, im from the UK so im performing on the UK itunes and was able to get it working at 22:18 (UTC)
