I don't get any candidates while testing my STUN & TURN server (CoTurn) with Trickle ICE on a MacBook 10.12.6 using Chrome 62.0.3202.89:
https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/
with:
stun:<ip-adres>:3478
turn:<ip-adres>:3478 [username:test]
On Digital Ocean I created a droplet Ubuntu 16.04.3 x64 and installed CoTurn version 4.5.0.3 doing:
sudo apt-get update
sudo apt-get install coturn
By default the firewall is inactive.
Next, I edited sudo vi /etc/turnserver.conf and give the following options:
fingerprint
lt-cred-mech
user=username:test
realm=<ip-adres>
listening-ip=<ip-adres>
relay-ip=<ip-adres>
external-ip=<ip-adres>
Next, I edit sudo vi /etc/default/coturn and uncomment the option:
TURNSERVER_ENABLED=1
Then I start the Coturn daemon:
sudo systemctl start coturn
sudo systemctl status coturn
This gives the output:
ā coturn.service - LSB: coturn TURN Server

Please help me, what is still needed here to let it work?
Starting doesn't work:
sudo systemctl start coturn
This seems like a bug.
To fix this bug:
sudo systemctl edit --full coturn
Delete everything and paste this:

After modifying the unit file, I reload the systemd process itself to pick up my changes:
sudo systemctl daemon-reload
Now starting actual works:
sudo systemctl start coturn
To make it automatically restart at reboot:
sudo systemctl enable coturn
