Hi, I face the same problem.
After install deb I start service with default settings, at local machine everything was ok, and i have access from localhost, but from outside i have "no living connection" error. I changed network.host to
104.199.112.18. after that i try to start and service crashed. Any changing network.host cause crashes: _local_ , 0.0.0.0. But when I just change port or comment setting all goings well. do you have any ideas?
