Can't set up shadowsocks in KDE

I am trying to set up the shadowshocks proxy.
I installed the shadowsocks-qt5 app and imported the proxy settings. It seems to be working because I can check the latency.
Then I try to set set it up in kde proxy app. In manual configuration I input in SOCKS. But when I attempt to use the internet I get ERR_PROXY_CONNECTION_FAILED.
What did I do wrong?
