SOCKS5 connects but no data is forwarded (hang)

[samansamie]

Hi,
I'm testing SlipStream-Plus and noticed that the SOCKS5 proxy (127.0.0.1:1080) accepts connections but does not forward any data.

Reproduction
curl --socks5 127.0.0.1:1080 https://google.com -v
CONNECT succeeds
But the request hangs indefinitely (no response)

Important detail
Connecting directly to the internal instance works fine:
curl --socks5 127.0.0.1:<instance_port> https://google.com -v

So the issue seems to be in the SOCKS forwarding layer, not the tunnel itself.

Expected
SOCKS proxy should fully relay TCP streams like the direct instance.

Let me know if you need logs or further testing.
