Unassigned; the middle port of the unnamed 34571-34573 run.
There is no IANA assignment for 34572 and no service name in Nmap's database, which measures it open on about 0.04% of scanned hosts. Anything answering here was configured by hand or picked by an application at runtime. It also sits inside the Linux ephemeral range, so short-lived client sockets land on it by chance.
