But a packet filter could.

Under /var/log/. Maybe /var/log/messages or /var/log/syslog. Have a look
at your sshd_config and your syslog config. The default is auth.info. And
also look for auth.debug. The actual files depend on your sshd
configuration and your psyslogd configuration.

Usually many/most versions of sshd will report the tcpwrappers issue
via the -d debugging. (This has hit me many times on many hosts using
various operating systems.)

Hopefully, that is all it is; so try in /etc/hosts.allow:
sshd: ALL : ALL
