I am having troubles logging into my iTunes account. Every time I log in I get the following error message...

"We could not complete your iTunes Sore request. The network connection timed out. Make sure your network settings are correct and your network connection is active, then try again."

I then ran diagnostics and was given the following error message...

"Network interfaces verified"
"Internet connection verified"
"Secure link to iTunes failed"

So. I can see the iTunes store within iTunes but I cannot interact with it so that I can purchase anything.

Upon researching this on the internet I have been told many different things, all of which I have tried with no success.

- Reinstall iTunes
- Flush DNS
- Allow exception in Anti-Virus software
- I actually completely removed it for the time being and I also downloaded the Norton Uninstall wizard because my previous anti-virus was Nortons. It currently is Kapersky.
- Allow exception in Windows Firewall
- Actually turned it off and tried it with no success. The exception was already there.

After all of that I did find one thing that allowed me to connect successfully and that was to connect to the VPN at my office. Once I am one the VPN then everything is good. But when I am off the VPN it doesn't work.

So that leads me to my router. My router is a Airport Extreme. I have completely reconfigured this as well with a full hard boot reset.

I am left with no ideas... Any help would be much appreciated.

I think that you need to look at your router settings. It seems that the most successful suggestion is to put your pc in the DMZ. I don't know if the aiport supports this, but most routers do have this option. It seems that the router has an internal firewall that is interfering with the connectivity.

Per MacNN:

Instead however, some users are seeing either an "-15000" or "-3526" error, where previously AirTunes functioned properly. The latter appears to be connected to firewall settings, and may be fixed by either giving iTunes access permissions, or disabling a firewall entirely. Apple states that the -15000 error may be triggerable by outdated Express firmware (prior to v6.3), but not all users are reporting success after updating. Some suggest unblocking UDP traffic, once again accessed through the Firewall pane.
