Cannot access certain websites on any web browser

Recently, for the last month or two, my mac won't let me look at certain websites. (i.e apple.com, hulu.com, some yahoo.com sites.) Cannot find a solution on any forums yet that work for me. The internet works fine on the other computers in the house and I can access those sites with no problems. I have snow leopard on my Macmini, and I tried reinstalling it and the websites worked ONE time, then if I closed the browser the sites would come up with the error, cannot connect to the internet. Or in the case of the Hulu site, show text only with no formatting. I also tried reinstalling Java, and it did the same thing, would let me see the website once and then not again. Not sure what else I can try. Does anyone have any suggestions? Is there some update i have not installed yet that does not come up in my updates? Thanks for all help.

First Gen. MacMini, Mac OS X (10.6.5)

I think I have a fix for everyone. I found and modified the following AppleScript to Kill PeerGuardian, disable filters, and kill of all of its background processes. If you compile it, then set the application to run on startup, it will make sure PG is not blocking anything. Then you can still choose to run PG as an app when you want, and just run this KillPG script again to shut it down and permit access to all of the aforementioned sites. Just copy and paste the code below into your apple script editor, compile and save it as an .app in your applications folder, and then add as a login startup item under Settings->Accounts->User Name-> and press the + to add and activate your new app on login:

delay 5

on isRunning(appName)
tell application "System Events"
set isAppRunning to (name of processes) contains appName
return isAppRunning
end tell
end isRunning

if isRunning("PeerGuardian") = true then
do shell script "killall PeerGuardian"
end if

if isRunning("pploader") = true then
tell application "pploader"
set filters enabled to false
end tell
do shell script "killall pploader"
end if

if isRunning("pplogger") = true then
do shell script "killall pplogger"
end if

if isRunning("pgagent") = true then
do shell script "killall pgagent"
end if

After alot of Google searching I finally figured it out.

This is straight from the developer:

In the "list manager" select to "allow standard ports" for all the block lists.

Wow. Thank you. This issue was driving me crazy. I wasn't having this problem before the latest software update so there must have been a clash between the update and the peer guardian settings.

I was trying everything under the sun including DNS/TCP/IP ping, malware, etc.

That was a huge headache. Thanks for helping out!

Your welcome and it took quite a while for me to find the answer searching online, so I figured I would help everyone to not go through the same headaches 🙂

I just started this job and I was having the exact same trouble and I really needed to access my email but was having major problems and it was driving me craaaaazy.

I can't thank you enough for this solution, and as such I even created an account on this forum to say thanks 🙂

This thing hapens to me weeks ago...as ive tried all possible solution nothing has changed.. one day, i resolve this problem of mine... and the culprit.. peerguardian... if you have peerguardian installed to your mac.. maybe this will work for you..go to peer guardian menu bar, choose list manager, check box " active & allow std port "on P2P and Ad on..

Someone please explain. How do I get to the "list manager?" What is "peerguardian?" Is it a standard part of Mac OS? How can I tell whether it is installed? Running?

My problem matches the description of this thread. The browsers complain of failed DNS lookups, but ping by name works.

Sep 19, 2012 3:54 AM in response to RockStarInLife

Thank you so, so, so much for this.

yeah, but its not being blocked because I can access it from my macbook pro since chrome is still supported with 10.6.8! its just that the software is too old to make most sites work properly.

May 7, 2015 10:43 PM in response to k.panic

In my case the problem is isolated to a MacPro. My MacBookPro on the same network has no problem.

I just spent hours on this, trying various solutions, talking to tech support, getting lost in tech jargon. What fixed it? Clearing my DNS cache. Instructions here: Reset the DNS cache in OS X - Apple Support

You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.

What OS version and what Safari version are you using?
