Safari 5.1.3 cannot access https://referees.aps.org/Referrals/login /new. Firefox does this with no trouble, so there is nothing wrong with the site. If this is not resolved I will (once again) have to abandon Safari. Can anyone help?

John...

Use OpenDNS for better speed, more security, includes anti phishing filters, and it's free.

Open System Preferences / Preferences then select the Network tab. Click the Advanced tab then click the DNS tab.

Click +

Enter these numbers exactly as you see them here.

208.67.222.222

Click +

208.67.220.220

Then click OK and restart your Mac, launch Safari.

If that didn't help, just go back to the DNS tab and delete those numbers.

I'm not having any problems accessing either site on Safari 5.1.3, Lion v10.7.3 and OpenDNS.

Tip: Most folks running Lion seem to have better luck with Safari by disabling the Lion "resume" feature.

Open System Preferences > General

What exactly happens when you try to open those sites?

Launch the Network Utility application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top) and press return.

☞ In the Finder, press the key combination shift-command-U. The application is in the folder that opens.

☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Network Utility in the page that opens.

Select the Lookup tab and enter

referees.aps.org

in the address field. Press return. Post the output – the text, please, not a screenshot. Then select the Ping tab and do the same.

Launch the Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, press the key combination shift-command-U. The application is in the folder that opens.

☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.

Drag or copy – do not type – the following line into the Terminal window:

curl -I https://referees.aps.org

Press return. You should almost instantly get several lines of output below what you entered, the first of which begins with something like this:

HTTP/1.1

If there's no output within ten seconds, consider that a failure. You can then quit Terminal.

Please read this whole message before doing anything.

This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.

Step 1

The purpose of this step is to determine whether the problem is localized to your user account.

Enable guest logins and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.

While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.

As Guest, test. Same problem(s)?

After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

Step 2

The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:

• Be sure your Mac is shut down.
• Press the power button.
• Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
• Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.

The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

Test while in safe mode. Same problem(s)?

After testing, reboot as usual (i.e., not in safe mode.) Post the results of steps 1 and 2.

Select  ▹ System Preferences ▹ Network ▹ Advanced ▹ Proxies. If any boxes are checked, uncheck them, apply your changes, and try again. You must apply the changes before they take effect.

johngar, I remember this conversation from a few weeks ago. As before everything points to a problem with your proxy server.

I understand this works for you when you run Firefox, but it is still working for me with Safari. Here is a screenshot of my proxy settings:

So the question everyone ought to be asking is why does this site load for you with Firefox, but not Safari?

Unfortunately I still do not have an answer.

You posted this same question on Feb. 10, you were given the right answer, and then you just disappeared without bothering to acknowledge it. I wish I'd known that before I wasted my time on this thread. Won't happen again.
