Thanks Michal. From using the dig command, it seems clear that what my ISP is providing is not a working DNS server. I have changed my top level router to distribute 8.8.8.8, 8.8.4.4, and 1.1.1.1 as my DNS servers, and it appears to have propagated correctly.
I've set my /etc/resolv.conf to just 'nameserver 8.8.8.8' and ran 'sudo /etc/init.d/dns-clean start'. I ran the tcpdump as 'sudo tcpdump -w /tmp/dump.pcap -s 0 udp and port 53' in case the requests go somewhere else by chance. Right now I'm having difficulty getting "good" logs. At first, all I was getting was 'server not found' with nothing in my pcap, so I thought I had messed up something. Now I'm getting only successful resolutions. I'll try again in a few hours. -- 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
