Unknown Error 310 when I try to log into my ITunes Account

THANK YOU SO MUCH!! your advice fixed my issue 😀😀

(went to my mac's network preferences, then advanced, then proxies, then unchecked everything except auto proxy discovery)

I had this same problem and discovered that my proxy settings for my network connection were wrong. To fix, I did the following:

1. Clicked on wireless network icon in upper right of screen

2. Selected "Open Network Preferences"

3. Selected the network interface I was using - in my case Ethernet

4. Selected the Advanced button in the lower right

5. Selected the Proxies Tab

6. Corrected my proxy server settings - in my case I did not have a port number set for my HTTPS proxy server.

From what I can tell, Itunes uses both HTTP and HTTPS protocols to connect to Itunes Store and to log in to Itunes Account (respectively). If you are on a network that requires you to use a proxy server, then you will have to make sure each of these protocols is set to use the correct proxy server URL and Port Number. Also, if you are on a network that does not use a proxy server, you need to make sure you don't have a proxy server set for these protocols.

Ideally, the proxy server settings are handled for you automatically when you connect to a new network, this isn't alwys the case however. Some older network don't support automatic configuration of the proxy server settings and you are forced to manually set the configuration. Most wireless and home networks I've run into don't use proxy servers, they are typically only used in large corporations to reduce network load on the intranet, or to manage external security threats.

Good luck

thanks much for everyone! its working!)

best response from jmasson, works for windows too.. went to internet options / advanced and unchecked both the HTTP options. iTunes works now. Thanks.

I checked my internet options and both the http & https are checked. Is there another place where I may need to check these as well?

I am online so I don't understand why it tells me it cannot access the internet. I am on a LAN at work.😕

Ive Been having the same problem where it dosn't show pictures on the itunes store

Thank you, worked for me. What would we do without Google and people like yourself 🙂

It worked!!!! You rock!!! Thank you!!

the broblem is very big

Just found this post with the same problem but none of the above answers seemed to work for me (I'm on the dreaded Windows 8) A little late, but hopefully this can help others with the same problem that find this post. If your other web browsers (Google, Mozilla, etc) can function normally online, but your iTunes won't connect, odds are there's a connection problems with Internet Explorer. Here's a little step by step that might be more clear:

1) Open up Internet Explorer and you'll probably get a "Poxy Server Isn't Responding" message.
2) If that's the case, go up to "Tools" in the browser tool bar select "Internet Options".
2) In "Internet Options" window that pops up, click the "Connections" tab at the top.
3) Click "LAN Settings" near the bottom of the section.
4) If the "Proxy server" checkbox is marked with a check, click to uncheck it.
5) Click "Ok" to close the "Local Area Network (LAN) Settings" window.
6) Click "Ok" to close the "Internet Options" window
7) Either refresh the page or close and re-open Internet Explorer, it should be working now.

This worked for me and now my iTunes is functioning again, so hope that helps anyone else who sees this! Sorry if this is exactly the answer that most were saying, I just feel it's easier when put into steps (:
