It looks like it happens almost exactly 10 minutes after a connection<br>
was established. I suspect that there is a firewall or NAT device in<br>
front of the client that drops any TCP connection after 10 minutes,<br>
regardless of whether there was any recent traffic over that connection<br>
or not. There is not much tinc can do about that, besides reconnecting<br>
when it happens.<br>
