Is this behavior to be expected? I also try to run via baremetal (on other system) using docker and works well.

I have no idea what would cause this. The correct arguments are being passed, unless your PHP binary doesn't support IPv6 then I don't understand the problem.

[dktapps]

You can try setting enable-ipv6=off in server.properties as a workaround.

[catzy007]

The workaround you provided works absolutely fine.

Thank you.

Please leave this open until it can be investigated properly.
