"transmission-cli magnet:?file" downloads the file that I want, how would I do the same thing using "transmission-remote"?

I have a script that downloads an iso using transmission-cli, but while searching for information on another transmission command issue, I find this So I can do this:

transmission-cli magnet:?xt=urn:btih:375ae3280cd80a8e9d7212e11dfaf7c45069dd35&dn=archlinux-2023.02.01-x86_64.iso

But I can't do:

transmission-remote magnet:?xt=urn:btih:375ae3280cd80a8e9d7212e11dfaf7c45069dd35&dn=archlinux-2023.02.01-x86_64.iso

Trying to do this:

transmission-remote -a magnet:?xt=urn:btih:375ae3280cd80a8e9d7212e11dfaf7c45069dd35&dn=archlinux-2023.02.01-x86_64.iso

results in this:

transmission-remote:  (http://localhost:9091/transmission/rpc/) Couldn't connect to server
