Can't use IPv6 on OpenBSD

[2anser]

Hello!

I tried to install AdGuard Home 0.107.72 on OpenBSD 7.8, but I'm having some difficulties in connecting to dashboard using IPv6.
It is perfectly configured, but after installing AdGuard Home using the curl command in GitHub, I try to open the dashboard using IPv6 but I get the error "ERR_CONNECTION_REFUSED", but works fine with IPv4. The same happens if I enable encryption and try to connect using only AAAA records, but I can connect with A records. What am I doing wrong? I don't have this problem on FreeBSD and Linux. Thank you!
I tried to look at the .yaml configuration but nothing seems to work. I tried to add [::]:80 in http, along with the default 0.0.0.0:80 but it breaks the dashboard at all.
