Error: Temporary failure in name resolution

[Jojioe]

Hi!
When I'm trying to ping dns names I have an error:

ping google.com

Output:

ping: google.com: Temporary failure in name resolution

But when I'm pinging IP adresses everything is okay (local IP in example):

ping 10.66.2.28

Output:

PING 10.66.2.28 (10.66.2.28) 56(84) bytes of data.

I saw this thread: https://forum.proxmox.com/threads/temporary-failure-in-name-resolution.133176/
But in my case, I got this:

cat /etc/resolv.conf

Output:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "resolvectl status" to see details about the actual nameservers.

And when I run "resolvectl status" I got this output:

-bash: resolvectl: command not found

So, what I have to do to be able to ping dns names?

Add your DNS to the /etc/resolv.conf or in the WebUI System | DNS
In the /etc/resolv.conf it should look like
nameserver 8.8.8.8

Hi,
assuming you're talking about a Proxmox VE node, you can set the DNS to use in the webGUI. There is a setting available for DNS

Did you install from promox iso or on an existing debian?

From proxmox iso

nameserver 8.8.8.8

Thank you! I'll try it

Thank you! I'm working with server remotely, so, is there any chance that if I write standard google dns 8.8.8.8 I'll lose my remote access?

This changes the way your node resolves names and shouldn't have influence on how you're accessing the server.
