As the error message say, probably the server is not running. The public servers are not under the iperf3 team control, so you should probably try another public server. Alternatively retry tomorrow, as it may be that the server is under maintenance, which is usually done at the weekends.

By the way -p accepts only one port, so the right parameter should have been -p 5201 or -p 5202 or -p 5203.
