i recommend resvpn.net or alike proxies based on RESIDENTIAL WireGuard (OpenVPN) VPN based protocol with UDP support. no other proxies like https/socks5 protocol will works now. socks5 are easy to detect as proxy ... because those proxies not support QUIC http/3 protocol, that are most common browsers and sites are works on now.
you will have no luck with socks5 for sure.
i wish i can give you here some test URLs where you can test yourself as proxy user,.. but i dont think if links to checkers are allowed here. you may found yourself.
