Could you please put only "nameserver 217.23.2.11" to /etc/resolv.conf and provide HTTP log (the same as in comment #13) and dump of DNS packets when the failure happens? Use tcpdump to dump the DNS packets:
sudo tcpdump -w /tmp/dump.pcap -s 0 udp and port 53 and host 217.23.2.11 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1796979 Title: Intermittently can't connect to the server To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1796979/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
