How to connect to FTL.sock?

I'm exposing FTL.sock from a Docker container to the host.
I'm trying to connect to it with the command:

sudo socat - UNIX-CONNECT:/home/user/sockets/FTL.sock

But nothing seems to be displaying, even when I type stats in.

When I try ABSTRACT-CONNECT I my connection gets refused.

Not sure if I'm going about this wrong or there's something specific about the FTL socket which is causing the issue. I've never used Unix socket files before so sorry if it's not strictly an FTLDNS issue.

Thanks.
