Connection error: connect ENETUNREACH xxxx:xxxx:xxxx:xxxx::1:22 - Local (:::0)
The same address works from a Linux terminal (ssh user@xxxx:xxxx:xxxx:xxxx::1).

Let me fix this issue right now.

The root cause of Termix-SSH/Termix#508 is that Docker containers do not have IPv6 networking enabled by default. When the Termix server runs in Docker and a user connects to an IPv6 host, the OS returns ENETUNREACH because no IPv6 route exists in the container's network namespace. The previous generic error message gave no indication of this.
