<br>
Even if I reconnect the interface, tinc does not continue.<br>
If I restart the service manually, everything works fine, even with disconnected network interface (it tries again and again until internet connection works).<br>
I think, there is some kind of boot-time race condition.<br>
It's the same problem with version 1.0.28 and 1.0.31.<br>
<br>
Do you have an idea how to find/solve the problem?<br>
<br>
<br>
Thanks,<br>
