there are several syncthing-clients on my LAN connected together with their LAN-IP. All are behind a NAT-router.
But one client repeats the following in its log:
It seems, that already local connected clients tries to connect the one client by its public IP.
How is that possible? Why does an already connected client tries to connect again?
Generally speaking, because it thinks there would be an advantage to doing so, but it’s impossible to tell why precisely without the information you blanked out. (Since these are all decisions about whether the IP is local or not etc)
