hidden service won't work with local ipv6 address
works fine:
HiddenServicePort 80 127.0.0.1:1234
doesn't work:
HiddenServicePort 80 [::1]:1234
Checked twice with a simple python http server: https://github.com/toralf/torutils/blob/master/websvc.py at a stable hardened Gentoo Linux (host speaks ipv4 and ipv6)
