If you are using ssh with mintty add "-h never":

-h, --hold[ |=]never|start|error|always
~/.minttyrc, /etc/minttyrc Hold=never|start|error|always

man mintty notes ssh returns 255 on connection errors

QA/testers may prefer to run tests in a tty using script, or some test tool,
rather than redirection, in what could be a background shell.
