Original GitHub issue: https://github.com/netbirdio/netbird/issues/4913

Describe the problem

I cannot connect/ping to a peer with the internal/DNS name as shown in the WebUI (https://app.netbird.io)
I can ping to the assigned IP address.
I installed the client on 2 other peers and the can ping each other via the DNS name fine.

To Reproduce

Installed client with curl -fsSL https://pkgs.netbird.io/install.sh | sh
Started netbird up --setup-key xx-xx-xx-xx-xx
Execute ping mypeername.netbird.cloud
Got ping: mypeername.netbird.cloud: Name or service not known

Expected behavior

An answer from the ping command showing me a connection is possible and the name mypeername.netbird.cloud to resolve to an IP address.

As it stands now, I am forced to use the IP address of other peers on that peer to be able to connect with them.

Are you using NetBird Cloud?

I use netbird cloud

NetBird version

0.60.5

Is any other VPN software installed?

No

Additional context

The peer is running on a Hetzner VPS with Debian 12.12

I also tried to (de)install via apt-get
apt-get remove -y netbird
apt-get install netbird

FYI: I could not find a guide on how to properly and completely de-install the client. Perhaps I overlooked or missed the documentation on it but if it does not exist, please describe the process. Or have the client option deinstall available: netbird deinstall

Add any other context about the problem here.

Have you tried these troubleshooting steps?

Reviewed client troubleshooting (if applicable)
Checked for newer NetBird versions
Searched for similar issues on GitHub (including closed ones)
Restarted the NetBird client
[n/a] Disabled other VPN software
Checked firewall settings
