kdeconnect doesn't

[Gary Dale]

I keep reading wonderful things about KDEconnect but I've yet to 
experience them. My android phones can't see my Debian/Buster desktop 
and vice versa. Both devices are on the same network and I'm not running 
an internal firewall on my desktop.

I've been trying KDEconnect intermittently for many months, during which 
time I've had a couple different Android phones, but have yet to have 
any success. I have no indication of any other network issues on my home 
network.

Both IP addresses (phone & desktop) are assigned via DHCP, which is 
probably about as normal as you can get. Manually adding the desktop's 
current IP address to the phone app doesn't help either.

Any ideas?
