audio not moving between two tailscale nodes

[a-singer]

Before I say anything else, let me thank you for your work on this. I am deeply grateful, this is a program I have spent years looking for. The closest I have come to it is sonobus, which works, but the accessibility of which is a pain. I really appreciate all you've done on this. I particularly appreciate the fact that it works on Windows 7. My working connection, indeed, is from 7 to 10.
My difficult connection is between two ten machines and they are both on tailscale. The machines see each other, and I'm able to check the boxes to connect, but I am not able to get any sound from one machine to the other. What I see from one machine's log which looks like it has something to do with it is this

Would any other data be useful? Note that I am able to have audio pass between the machine and another on the LAN.

I know this is replying to my own issue but the problem was that the firewall was on the tailscale adapter and didn't let anything through. Other stuff worked fine but the firewall would not let Remsound through. Once off, Remsound worked. Feel free to close this issue, and thanks for the program.
