Yes, but psql 16.6 fails in the same way:

root@hetzner-2:~# docker run -it postgres:16.6 psql 
"host=headcrashing.eu port=5432 dbname=postgres user=postgres 
password=HeadcrashingPostgres2022 sslmode=require"
psql: error: connection to server at "headcrashing.eu" (49.13.53.107), 
port 5432 failed: SSL error: tlsv1 alert no application protocol
