Error 102 (net::ERR_CONNECTION_REFUSED): Unknown error - I've tried everything.

Long time reader at MacRumors, first time posting.
Here's the rundown of the issue I'm having:

About a week ago, I switched from DSL to a Cable Modem (10x faster, 50% cheaper... hurray, right?) and two days later my computer stopped connecting to the internet, or so I thought. It seemed I was unable to connect to google, or anything google-related, i.e. picasa, youtube, google reader, gmail.
My website uses google HTML snippets, which do not load (http://raisedby.tv)

• Using a 2006 15" MBP with snow leopard 10.6
• Most sites work fine.
• Getting the same error on
Safari 4 (Safari can’t connect to the server)
Firefox 3.6 (Unable to connect)
and Google Chrome (Error 102 (net::ERR_CONNECTION_REFUSED): Unknown error)
• No Google sites load.
• Yahoo opens maybe 50% of the time.
• Other computers on the network load google just fine.

Troubleshooting steps I've tried:
• rebooting my modem and router (duh)
• resetting my wireless router
• resetting my airport settings
• clearing my browser settings (all of them)
• flushing the dns cache with terminal command
dscacheutil -flushcache

I've tried everything short of a complete system restore. What am I missing guys?!

Thank you,
-Mhunterak

I had to open it on my iPhone, thanks for posting a link to the website I'm asking for help about. You know, because my computer isn't connecting to it. I've already tried the solutions they offer.

Webpage display issues: "This webpage is not available" (Network errors 2, 102, 104, and 105)Print
Issue

This message displays when Google Chrome is unable to find and load the requested webpage.

Solutions

Check your web address and Internet connection

Double-check the URL in the address bar to make sure you're going to the right web address. If you've confirmed that you're going to the right web address, check whether you can open the same webpage in another browser, such as Internet Explorer or Firefox. If you can't see the webpage in any browser, the webpage may be temporarily down. You should also make sure you're properly connected to the Internet.

Check the error you're receiving

If you can load the webpage using another browser, but not Google Chrome, check the exact error you're getting by clicking the More information on this error link on the page. The rest of the solutions listed in this article are relevant if you're experiencing any of the following errors:

Error 2 (net::ERR_FAILED): Unknown error
Error 104 (net::ERR_CONNECTION_FAILED)
Error 105 (net::ERR_NAME_NOT_RESOLVED)
Error 102 (net::ERR_CONNECTION_REFUSED): Unknown error

Check for malware

Clear your cookies

Make sure Google Chrome is allowed in your antivirus and firewall settings

Adjust your proxy settings

have you checked that your firewall is not blocking google for some unknown reason?

Have you installed any new software since your switch (particularly anti-virus, or "cracked" software)? If so, then uninstall, and immediately run a virus and malware scan and clean. then uninstall the anti-virus software and try again.

You said all computers on the network can get to google fine. Are they all running through the Airport and the router, or just the mac?

Same problem

I'm having the same problem. No solutions for macs are out there. Did anyone ever get an answer to this? It's killing me not being able to use google. Tried every browser. It has to be in the network settings.

May be a long shot, but have you tried switching the DNS servers to Google-- 8.8.8.8 and 8.8.4.4? I have Time Warner, and sometimes TW's DNS stuff just gets inexplicably shot to heck. When I go into the router settings and change from the TW's DNS servers to Google's, joy returns. Worth a shot.

Same problem here. Macbook with OS X 10.6.6. No change in setup or software, came home from work yesterday afternoon and now google (all sites), youtube, yahoo, and many others get ERROR_102. Same in all browsers. Others connected to the same wifi router can still connect as normal. Whats going on? Apple? Google?

Still no luck for me. No one in my house or at my office has this issue (two different service providers also), but I think it is interesting this happened to everyone at the same time.

Update:
Still no luck for me here either.
Still able to access various other websites, so connection is intact.
- Firewall is disabled.
- Parental controls disabled.
Tried clearing the DNS cache with:
Code:
dscacheutil -flushcache
but this made no difference.

I DO get a response if I ping www.google.com, but traceroute does not work. Results below:

Code:
$ ping www.google.com
PING www.l.google.com (74.125.237.20): 56 data bytes
64 bytes from 74.125.237.20: icmp_seq=0 ttl=52 time=368.409 ms
64 bytes from 74.125.237.20: icmp_seq=1 ttl=53 time=338.086 ms
64 bytes from 74.125.237.20: icmp_seq=2 ttl=53 time=319.346 ms
64 bytes from 74.125.237.20: icmp_seq=3 ttl=53 time=328.449 ms
Code:
$ traceroute www.google.com
traceroute: Warning: www.google.com has multiple addresses; using 74.125.237.20
traceroute to www.l.google.com (74.125.237.20), 64 hops max, 52 byte packets
traceroute: sendto: No route to host
 1 traceroute: wrote www.l.google.com 52 chars, ret=-1

This could well be the most annoying computer problem I've had in years...hope someone can find a solution soon.

Are there any other steps that I have not tried to clear the DNS cache etc?

I had the same issue - started two days ago. Drove me crazy and tried everything.

Fixed it today by disabling an IP blocker that I installed a year ago called PeerGuardian.

Hope that helps!

Great to hear some of you have had success by disabling PeerGuardian. I have managed to fix the problem by deleting the contents of the following folders:

/Users/UserAccount/Library/Caches
/System/Library/Caches

Restart your computer and voila!

I found this and other suggestions in this thread on Apple Discussions.

Hope you all manage to get Google back

Error 102

Hello, MacRumors

I have been a reader of the forums, however I decided to join MacRumors because of this issue. Recently, my browsers became unable to view any google affiliated websites. Google chrome rendered Error 102 like all of you have written. I have fixed my problem last night and wanted to share my solution.

I am an Ableton Live user and Max/MSP programmer. I demand a lot out of my computers memory and usage. Pretty much each week, I optimize my computer, erase my cache, and maintain my computer for efficient live performances.

The software I use to perform this is Snow Leopard Cache Cleaner. My problem developed after I had interrupted a optimization of my computer.
I didn't put two and two together, shortly after this, I could not view google affiliated websites.

I read this forum, I disabled PeerGuardian, deleted my cache like the poster above suggested, then I repaired my permissions, optimized my memory, and cleaned my cache. When, I started my computer this morning, boom, I was back into my gmail and left to read hundreds of emails I was restricted from for the weekend. I haven't enable PG yet, I will post later if PG is an issue. I hope this helps and I hope google becomes more aware of this problem because I seems to be sourced around Chrome and is both Mac and PC related

Lion Restore - yahoo.com doesn't work

This fixed all of my problems - deleted corrupt PeerGuardian and all is well again.
Thanks,!!
