I have a 2010 MBP. Just in the last day or so, whenever I try to browse to Facebook (www.facebook.com), I get a ERR_CONNECTION_REFUSED error.
This is what is displayed in Chrome, however I cannot connect in Safari, Firefox, nor
curl -o fb.txt http://www.facebook.com from the command line.
As far as I can tell no other websites are affected. In fact, developers.facebook.com and graph.facebook.com work just fine.
Things I've tried:
- What Chrome tells me to do.
- Deleting the browser cache.
- Restarting the computer.
- Shutting down the computer, and rebooting.
- Clearing the DNS cache.
- Using a different Wifi network.
- Using a wired network (and turning off Wifi).
Running Wireshark shows that the Facebook server (18.104.22.168) is returning a "Destination unreachable" ICMP packet whenever I browse.
No other computers or mobile devices on my network are affected, just the MBP.
I'm at a loss as to what to try next! Any suggestions appreciated.
I'm wondering if my network stack is somehow corrupted?
