Hi Johannes!Romeu
Thank you very much for your help!
We ran dtnd again on interface wlan2, making sure there were no other instances running, but we got the same errors.
The output of the netstat command is:
root@VeniamWorks639:~# netstat -l -n -p | grep dtnd
tcp 0 0 127.0.0.1:4550 0.0.0.0:* LISTEN 2109/dtnd
tcp 0 0 ::1:4550 :::* LISTEN 2109/dtnd
