(As Carl Eugen wrote, please also show the complete, uncut console
output.)

The "Protocol 'rtp' not on whitelist" was an ffplay error, so you need
to add those options to the client ffplay command line, not to the
server's. (You may also need the protocol "udp".)

I can reproduce your error. If I add that option (plus "udp") to
ffplay, the error goes away. I get a different issue then, but YMMV.
