It is looking like your mythbackend is not responding to port 6544.
Try running this on your Buster server:

netstat -anp | grep 6544

This is what I get - it shows mythbackend listening on TCP port 6544
on all IP addresses on IPv4 and IPv6:

root at mypvr:~# netstat -anp | grep 6544
tcp        0      0 0.0.0.0:6544            0.0.0.0:* LISTEN
2731/mythbackend
tcp6       0      0 :::6544                 :::* LISTEN
2731/mythbackend
