Hi all I have the same issue this a cygnus ngsi used has service

agent_1.conf

listening port the Flume source will use for receiving incoming notifications

cygnus-ngsi.sources.http-source.port = 5050

cygnusinstance1.conf

Administration port. Must be unique per instance

ADMIN_PORT=8081

tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1/systemd tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 13622/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 13771/master tcp6 0 0 :::111 :::* LISTEN 1/systemd tcp6 0 0 :::8081 :::* LISTEN 5035/java tcp6 0 0 :::22 :::* LISTEN 13622/sshd tcp6 0 0 ::1:25 :::* LISTEN 13771/master

No process listing on 5050 !

Any explanation ? Thank you for your feedback
