I have problems with facebook and gmail only: It works fine and lets me log in, view the content, read new messages, etc. But after 5-10 minutes it doesn't load at all:
This webpage is not available.
The webpage at http://www.facebook.com/ might be temporarily down or it may have moved permanently to a new web address.
More information on this error Below is the original error message
Error 101 (net::ERR_CONNECTION_RESET): Unknown error
After deleting cookies this problem disappears for 5-10 minutes, then I get the same error. It happens with Google Chrome and Firefox. Ping works fine.
I have checked System → Preferences → Network Proxy, it's set to the default: "Direct Internet Connection". Then I ran the test at
chrome://net-internals/#tests and got some "FAIL" results
- Use system proxy settings
- Disable IPv6 host resolving
- Probe for IPv6 host resolving
IPv6 is disabled.
