proxychains Set multi-level agen,tor as a proxyheader has problems

[cbedhoam620]

socks5 127.0.0.1 9050
socks5 PROXY2 1080
socks5 PROXY3 1080

I use proxychains -f /etc/Torproxylist.conf curl ident.me, happen "socket error or timeout".

But it doesn't matter if I use any of the proxies in the proxy chain alone, or if I comment out Tor's proxies, the rest of the proxies can still form the proxy chain
