I'm having problems using Back To My Mac from work to my home network. Initially, I thought it was something to do with the way the work network had been set up, but recently I realised that I have no problems connecting to my Time Capsule… It's just that I can't connect to my MacBook Pro. It is showing up in the devices on the left panel, but when I try to connect to it, I get this message:
So why is it I can connect to the Time Capsule HD okay, but not the Mac?
UPDATE 1: I'm not sure if it's relevant, but I do get a warning message on my work connection: However, this states that the connection might be slow, not non-existant. I have no control over how the work network is setup, but considering I can access the Time Capsule at home, I don't imagine this is the problem.
My home machine is running OS X 10.8.2 and my work machine is running 10.7.4.
There are certain troubleshooting tips that deal with Keychain Access if coming from MobileMe to iCloud. I will look into this next.
