Q: iCloud server not responding

Same here.

Same here. MacBook Pro 17" 10.7.4 and MacBook Air 10.7.4. Neither can access Back to My Mac even though both were accessing it fine a few days ago.

Same with me. My MacBook Pro gives me that server is not responding. I have re-started everal times to no avail.

HELP

Same here, and the iCloud status page is reporting all services working...???

This is why I really hates to be an Apple user.  When you get used to one product, they then change to a newer one.  You not only have to upgrade your existing product, but also you have to suffer from many other headaches coming with the new product.  SOmetimes I wonder whether this is how Apple makes its money.

Here's someting crazy. While at the office and unable to connect to Back to My Mac, I noticed my home computer showing up under Shared. I shared its screen (successfully), opened System Preferences, and saw the error message we are all seeing.

It seems to be a logon issue. When I got home and tried connecting from my home computer I again got the message that the server is not responding. It seems once you log off from Back to My Mac (or put your computer to sleep), you then have the problem of not being able to connect.

I was having the same problem but found a solution that worked for me.

1. From the iCloud System Preferences pane, uncheck the Back to My Mac checkbox to turn it off.

2. Open the Keychain Access app (in Applications/Utilities).

3. Click the "System" keychain (You'll see keychains near the upper left of the app window).

4. Make sure "All Items" is selected in the "Category" box below.

5. In the results showing to the right, look for any key whose "Kind" is "Back to My Mac key."

6. Delete the key(s), authenticating with your password to do so.

7. Back in the iCloud System Preferences pane, re-check the Back to My Mac box.

At this point, Back to My Mac started and the "server not responding" message did not appear.

I'd tried unchecking and re-checking several times before to no avail. I hope it works for everyone.

Maybe the keys we had were tied to MobileMe and became invalid when MobileMe shut down?

This tipp solved the problem for me too.

Thank you, Bladdernose
