Merge pull request #6 from MarekWojt/features/fixes

Fixed:

- missing response text on authentication failure
- missing response text on internal server error
- updating ipv6 via request for updating both ipv4 and ipv6 didn't work, could reset previously set ipv4
- domain list in auth.toml needed "." suffixes
