Hi!
I am using unbound for DOT on FreeBAS 12.2 desktop computer. It
works but I have about one month when unbound start libunbound errors:

[1608331195] libunbound[20481:0] error: udp connect failed: No route to
host for 2001:503:c27::2:30 port 53 [1608331195] libunbound[20481:0]
error: udp connect failed: No route to host for 2001:500:9f::42 port 53
[1608331195] libunbound[20481:0] error: udp connect failed: No route to
host for 2001:500:200::b port 53

I had the same question two days ago. See the the following thread:

https://lists.nlnetlabs.nl/pipermail/unbound-users/2020-December/007123.html

In the meantime add the following line to /etc/rc.conf:

unbound_anchorflags="-4"

Thank you very much.
