Problem with DDNS scripts no-ip?

I've set up ddns-scripts with I'm using 19.07.03, fresh (no saved settings). I add all my info, but I get uclient-fetch error '8' in the logs. So I try copy/pasting the output of the command from the log and get an http error 401. The command used address as the update address.
When I go to their support says the following address is correct:
I run the same command from command line, substituting the address from and it works. Is it possible that script needs to be updated?

Are you using the USA service, or the Polish service?

I think you set the wrong No-IP.
