I upgraded to Utopic yesterday, and ever since I've been encountering errors like these:
- Chrome:
Error code: DNS_PROBE_FINISHED_BAD_CONFIG
- apt-get:
Cannot initiate the connection to security.ubuntu.com:80 (2001:67c:1562::13). - connect (101: Network is unreachable) [IP: 2001:67c:1562::13 80]
- Steam client:
Error Code: -137 Failed to load web page (unknown error).
I, so far as I know, have made no changes to any network configuration on either my computer or my router.
This issue is particularly odd, since it seems to only affect certain websites. To make it even weirder, if I hit refresh enough, the connection will eventually go through.
Here are some sites I've encountered it on:
- launchpad.net
- store.steampowered.com
- security.ubuntu.com
And some sites where it didn't happen:
- www.ubuntu.com
- steamcommunity.com
- google.com
- askubuntu.com
Not sure if this will help, but here's the output of ifconfig
