websites - dns_probe_finished_nxdomain error caused by Ubuntu - Ask Ubuntu


i've been having strange error dns_probe_finished_nxdomain error whenever try navigate outlook.live.com on ubuntu computer. happens in firefox, chrome, , curl in both regular , private/incognito modes. i've tested on multiple wifis , still same error. haven't tested ethernet yet, if need me can. make sure wasn't problem hardware, tested windows 10 on same machine. there no errors in case. can conclude problem ubuntu itself, particular installation.

computer specs:

  • model: lenovo g50-70
  • os: ubuntu 16.04 lts
  • wifi specs:

i solved clearing dns cache on computer. think used command, i'm not 100% sure:

sudo /etc/init.d/dns-clean
