[BUG] Help PTR failed: all DNS requests failed

[ifoverload]

Describe the bug

Why im getting this debug logcat:

[DNS Server] Exchange ;2.0.0.28.in-addr.arpa. IN  PTR failed: all DNS requests failed, first error: all DNS requests failed, first error: dial udp6 [fe80::7a85:f4ff:fe96:d693]:53: connect: invalid argument

As a result ipv6 just fail from test. Is my configuration wrong? How to fix?
