How to fix error 405 itunes

From http://support.apple.com/kb/TS3297

iTunes Store loads partially or returns "Error 306" or "Error 10054"
Proxies, parental control settings and software, security or filtering software, or a bad iTunes Store cache can cause this.
To address proxies, Remove Internet Options proxy settings and connect to the Internet without a proxy.
To reset iTunes Store cache:

1. In iTunes, choose iTunes > Preferences (Mac) or Edit > Preferences (PC).
2. Click the Advanced tab.
3. Click the "Reset cache" button.
4. Click OK and see if the issue is resolved.

Adjust Parental Controls in iTunes:

1. Open iTunes.
2. Access iTunes preferences:
   1. On a Mac: From the iTunes menu, choose Preferences.
   2. On a Windows PC: From the Edit menu, choose Preferences.
3. Click the Parental Controls tab.
4. Remove restrictions on Parental Controls.

Hi Douglascole,
Error 450 happens when using iTunes as a user with Parental Controls applied to the account within the operating system.
Reduce the restrictions on the Parental Controls and consider using the Parental Controls feature of iTunes. http://support.apple.com/kb/HT1904

The 450 download error seems to be caused by either of two setups.

1. You are not allowed to download something because parental controls are in place or
2. You are using a 'user' account and not the 'administrator' account that is needed to download from the Internet.

It is not a firewall issue.

Please do be considerate when leaving positive ratings and feedback today. Thanks to the help of itunes for this solution as well.

Sometimes this error can be caused by software on your computer that slows down the network connection. This error can also appear if you are downloading multiple items. I'd like to provide some steps that should help you successfully download your purchases.

It often helps to pause the download and then download items one at a time. These steps will walk you through doing this:

1) Open iTunes.

2) From the Store menu at the top, choose Check for Available Downloads. If you're unable to upgrade and are using iTunes 7, the option will say Check for Purchases.

3) Enter your account name and password, then click Check. Your purchases should begin downloading.

4) Under the STORE section on the left, click Downloads.

5) Click the Pause All button in the lower-right corner. This will temporarily pause all of your downloads.

6) To resume only one of the downloads, click the refresh button that appears to the right of one of the paused downloads.

Certain types of software can affect the way a computer sends and receives information from the Internet. Here are a few examples of these types of software:

• Firewalls
• Web accelerators
• Ad filters
• Virus protection software

If you have any of this kind of software installed on your computer, you will need to configure each of the applications to allow your internet connection to access iTunes freely. For instructions, please refer to the documentation that came with that software, or contact the software's manufacturer. You'll need to configure the software to allow these domains to send and receive data from the Internet freely:

itunes.apple.com
ax.itunes.apple.com

For assistance in configuring your firewall or accelerator software, you may need to contact the manufacturer or your Internet service provider (ISP). When contacting their support representatives, it may be useful to have the following information:

The following article helps Windows users pinpoint software conflicts that could cause the error:

Once you have managed to allow access to iTunes through other software, please follow these instructions:

1) Sign out of the iTunes Store.

2) Quit the iTunes application.

3) Restart your computer.

4) Open iTunes.

5) Select Check for Available Downloads from the Store menu at the top of iTunes, (if you're unable to upgrade and are using iTunes 7, you'll choose Check for Purchases).

If you can't find this option, you can also click this link to do the same thing:

6) Enter your account name and password, then click Check. The missing item should begin downloading and appear in your Purchased playlist.

Please note that the iTunes Store cannot investigate every user's connection issue. Apple Discussions are another source of information about iTunes, where everyone from new users to professionals can interact and share their knowledge and experiences. You may find another user with the same operating system or ISP that may be able to help resolve this issue. You can find the iTunes discussions group at:

If you are using a dial-up connection, you might consider downloading your purchases over a broadband connection, if you have access to one.

Okay, I found the solution when running CA Security Center for me. You need to open your Parental Controls - Advanced Settings. In the user/default tabs select Web Filters. The select "Custom List" under the allowed section. Then add the following sites individually: itunes.apple.com, ax.itunes.apple.com, albert.apple.com Be sure to select the checkbox to allow the entire domain. Then restart iTunes.
