A I managed to find the problem thanks to somebody else finding it late
last year.
With the particular verison of Perl on the Pi (I think I said 5.28) there
is a bug for the IO::Socket::Multicast module:

Hi thanks for the response.
Before I continue, at the top of the script I first borrowed for this it
had "use 5.026;". When I remove this and then alter any "say" or "break"

while(1) {
my $conn = $sock->accept();
print <$conn>;
}
etc.
