Hi, I have 2 peers in a LAN, which are not able to communicate at all.
A third peer coming in over the internet can see both.
I will attach the log-files of the two peers not being able to connect via LAN
The log-file shows, that the peers are actually connecting, but the not agreeing on a cipher or something. I already tried to disable encryption on LAN sync. That did not help.
Cannot attach Files, so logs inline:
