I think my latest patch,
http://lists.infradead.org/pipermail/lede-dev/2016-December/004433.html
, should also fix this, since this is typically caused by IPv6
autoconnect being enabled and trying to disable it with IPv4 client or
vice versa. My patch adds separate commands for IPv4 and IPv6. That
said, I don't like the autoconnect at all, it being so unpredictable
across various models.
