If I add this to my launch daemons I get a "connection refused" error after restart of my Mac Studio running on Mac OS Ventura 13.1

The error log: "2023/01/24 17:12:43 socat[346] W refusing connection from LEN=16 AF=2 192.168.178.XXX:48416 due to range option"

All is working fine if I start socat manually by "socat TCP-LISTEN:2375,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock &"

Any ideas?

Solved the problem: I added the range-parameter to my socat arguments in launch daemon script. This leads to an error! Don't use the range-parameter in TCP-LISTEN on Mac OS!
