cannot connect, though same network, same connect-code

cannot connect two warpinator apps, though same network, same connect-code.

1. warpinator 1.8.3+virginia on "linux Mint" 5.15.0-144-generic
2. warpinator 1.8.2 on Android

• both on same network 192.168.66.* over fritz.box router 192.168.66.1
• both same connection code "zuhause"

I have added the log of Android app

warpinator-log.txt

Where could be the fault?

I had to turn on subnet routing in my phone's firewall for them to be able to connect. Until then, my phone could see my desktop, but not vice versa.

The Android log says that the Mint device is not connecting back to it, but it cannot know what is the problem. Could you provide a corresponding pair of logs from both Android and Linux?
