While trying to dig @8.8.8.8 google.com I'm getting:

connection timed out; no servers could be reached

Ping works, but I can't dig to any server. The firewall is off, and port 53 is open (TCP and UDP).

  • Your question is offtopic here as not related to programming but 1) do not use ping to troubleshoot DNS problems 2) try tcptraceroute to port 53 or traceroute -T udp or equivalent to really simulate DNS traffic 3) if you don't get reply it means something is filtering packets between you and remote side. – Patrick Mevzek Dec 12 '21 at 00:16
  • Please do this, and put the output in the question: **`dig @8.8.8.8 google.com +noedns +nocrypto +nodnssec +trace`** – James Risner Sep 20 '22 at 11:53

If you are ok with iptables and selinux; you must check all network services status once on your machine.

The issue I found is network.service ; was failing on the vm.
