Installed it on my : POP os, Ubuntu Mate (ARM ) and Raspberry pi OS (ARM) and mt Mint Cinnamon
20.3.

That's 3 computers and 4 OS.

Can anyone give a clue on when I did the Raspberry Pi And the Mint 20.3 that they can see each
other but could not connect ?

All the systems have 99.9 % same software, all have the same FW and VPN but these two
computers could not connect even after reboots, router reboots etc.

As soon as I installed on my POP OS did they start working. was there something different with
POP ?

Fantastic program by the way .

You have followed the suggestions on the warpinator window?

Those all are proper, if you mean the GitHub page, yes, as I said it finally worked and still works.
just didn't know why they connected once the POP OS came on board.

All that leaves me with now is getting and indicator showing when I minimize or close it and it's in
the background on the raspberry pi, using either Ubuntu mate or Raspberry OS.

It uses Zeroconf for nameserving, and the machines should be on
the same subnet. You can change the subnet mask, if you want to
span a larger range.

https://wiki.mageia.org/en/Warpinator

There has to be a mechanism, where they can "advertise" they're
running a server, to one another. The clients then look for server
instances, presumably using Zeroconf to find them. Maybe there's something
like Avahi underneath. (Perhaps the POP OS had Avahi ?)

https://en.wikipedia.org/wiki/Zero-configuration_networking

I couldn't figure out too much by just looking at the Warpinator source, and
nobody makes a nice block diagram with layers, to show the
control plane and the data plane. The port 42000 and 42001 is
probably not the whole networking story (those ports could be
for the data plane)

One of the dependencies listed for this thingy is python3-zeroconf.
Zeroconf is mDNS. mDNS means avahi.

Is avahi running on both machines?

sudo service avahi-daemon status

Yes running on all three, as I said they all work now, don't know why the pi and the acer didn't talk
to each other at first but they are now and I', happy.
