Original GitHub issue: https://github.com/netbirdio/netbird/issues/5214

Describe the problem

Specifically when connecting from Malaysia, the AAAA DNS entry seems to point to an address that does not respond.

To Reproduce

Steps to reproduce the behavior:

curl -fsSL https://pkgs.netbird.io/install.sh | sh from Malaysia

Expected behavior
Client should install, but the curl request times out.
In Malaysia, nslookup pkgs.netbird.io returns this IPV6 address: 2a04:3543:1000:2310:2465:1fff:fe8a:59d0
I have attempted to ping this address from other regions e.g. as well and it never responded.
Doing a DNS lookup in a different region returns 2a04:3542:1000:910:2465:1fff:fe8a:1d97 which does respond.
Adding a /etc/hosts/ entry for pkgs.netbird.io to override the IPV6 address to this one allows the script to continue

For some reason 2a04:3543:1000:2310:2465:1fff:fe8a:59d0 i.e. your Singapore IPV6 is not responding to requests

Are you using NetBird Cloud?
Yes

NetBird version
N/A, occurs while trying to install netbird

Is any other VPN software installed?
No

Debug output
N/A

Create and upload a debug bundle, and share the returned file key:
N/A

Alternatively, create the file only and attach it here manually:
N/A

If applicable, add screenshots to help explain your problem.
N/A

Additional context

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
Disabled other VPN software
Checked firewall settings
