I don't think your poblem is with systemd-timesyncd, it's with the
network.  You appear to have an unstable connection which is why it
keeps saying "Network configuration changed, trying to establish
connection."

Also that IP address doesn't work for me either:-

    chris@bbb$ host 2.debian.pool.ntp.org

I don't know why your system is trying 162.159.200.123 and not the
alternatives, mine seem to find a working IP OK.  Is your DNS good?
