I am not familiar with rebind logic here, so it is difficult for me to
make suggestions. But I would expect that bind and rebind addresses
should be the same. Not sure it should be hostname though. In your
case for example, before rebind the osd was listening on all
interfaces, and after rebind it was listening only on loopback,
i.e. it was accessible only from the local host.
