Setting up following this guide: https://mullvad.net/en/help/shadowsocks-android

And I have everything in OpenVPN and Shadowsocks set up like they say, but when I try to connect to the Shadowsocks server I get the error "Failed to detect internet connection: connection closed". The upload/download shows I can upload at ~30 kbps but no download.

I'm on MIUI 14 which may be the problem because I know it has some issues with...everything really... But I turned off power saver so it should be allowed to run in the background
