Original Pull Request: https://github.com/netbirdio/netbird/pull/4579

State: closed
Merged: Yes

Describe your changes

This change explicitly disables DNSOverTLS for the Netbird wg interface on systems using systemd-resolved. Currently, if the system has DNS over TLS enabled globally then netbird interface will inherit it and DNS resolution ends up in a broken state. Disabling dnsovertls setting explicitly for interface fixes this issue.
