The remote bash script run over SSH ended with a for-loop whose last
statement was `[[ "$n" == "$target" ]] && echo ...`. When the last
VM/CT checked on the node didn't match --host, that test evaluated
false and became the exit status of the whole remote script (1) --
which the wrapper then misreported as "couldn't reach the node",
even though SSH connectivity and the check itself were both fine.
The actual signal is the script's stdout, not its exit code, so end
it with an explicit exit 0.
