No IANA assignment and no well-known software — an unidentified listener if you find it.
IANA has no entry for 8385 on TCP or UDP; the neighbouring 8384 is Reserved on TCP and assigned to marathontp on UDP, which tells you nothing about this port. Nmap carries it as "unknown" with an open rate near 0.015%, among the rarest it tracks. Anything answering here is a locally chosen port — a second instance of a web UI, a container mapping, or a homegrown service.
Expose with care
Unregistered means unidentified. Name the process on the host, then decide; do not assume an unregistered port is harmless.
