Can't open Youtube on Safari

It's been about three days since youtbe suddenly stopped loading in my mac. It loads a tiny bir in the adress bar and when I wait a good few minutes it says that Safari can't open the page.

I've alreay tried several DNS settings but that doesn't seem to be the case. Also, none of my proxies are checked.


Any ideas on what may be the problem?

YouTube videos not playing?


One of the following steps should help.



1. Install Adobe Flash Player.


http://get.adobe.com/flashplayer/


Restart

2 .Are Plug-ins Enabled?


Enable Plug-ins


Safari > Preferences > Security


Web Content:

Click in the box for "Enable Plug-ins".



3. Check whether you are currently in YouTube HTML 5 trial.


http://www.youtube.com/html5


At the bottom left of the page uncheck the box for


"You are currently in the HTML5 trial".



Now try YouTube.


Best.

Select the text below (not including the blank space at the end of the line), then copy it to the Clipboard (command-C):


youtube.com


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.)


☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.


☞ Open LaunchPad. Click Utilities, then Network Utility in the icon grid.


Step 1


Select the Lookup tab and paste (command-V) into the address field. Press return. Post the output that appears below – the text, please, not a screenshot.


Step 2


Select the Ping tab and do the same.

You wrote above that you had changed your DNS settings, so I assume you know how to do that. In your router, change the DNS settings to use your ISP's DNS servers. Usually all you have to do to make that happen is to delete whatever you put in. The DNS server addresses should be populated automatically.


On the clients, also remove the DNS server addresses. Your router should then be used as a DNS proxy, which will refer all queries to your ISP.


Test. If there's no improvement, please repeat the Network Utility tests and post the results.

Hi. I have the same problem. My macbook pro doesnt open youtube in any browser (safari, chrome, firefox..). I tried the solution you gave us here but i cannot save the changes in the host file. Actually the file was locked to change anything but i gave permission. Then still it doesnt accept any change in the file. I am trying this on Textedit because I dont have smultron. So is there any other way you know, to solve this problem? thanks.
